Python’s regex capturing groups allow you to extract parts of a string that match a pattern.

• Enclose the desired pattern in parentheses () to create a capturing group.
• Use re.search() to find matches, and access captured groups with the .group() method or by indexing the result.

For example: match = re.search(r'(\d+)', 'abc123') captures the digits, and match.group(1) returns '123'.

---

One of the powerful aspects of Python’s regular expression capabilities is the use of capturing groups. By using capturing groups, you can easily extract specific portions of a matching string and efficiently process and manipulate data that meets a particular pattern.

I like to use capturing groups to isolate and extract relevant data from a given text. To define a capturing group, I simply place the desired regex rule within parentheses, like this: (rule). This helps me match portions of a string based on the rule and output the captured data for further processing.

Tip: An essential technique I employ while working with capturing groups is using the finditer() method, as it finds all the matches and returns an iterator yielding match objects that match the regex pattern. Subsequently, I can iterate through each match object and extract its value.

Before I’ll teach you everything about capturing groups, allow me to give some background information on Python regular expressions. If you’re already an expert, you can jump directly to the “capturing groups” part of the article.

Understanding Regular Expressions

As someone who works with Python, I often find myself using regular expressions.

Recommended: Python Regex Superpower [Full Tutorial]

They provide a powerful tool for dealing with strings, patterns, and parsing text data. In this section, I’ll guide you through the basics of regular expressions and shed some light on capturing groups, which can be extremely helpful in many situations.

Basic Syntax

Regular expressions, or regex, are patterns that represent varying sets of characters. In Python, we can use the re module to perform various operations with regular expressions. A key component of regex is the set of metacharacters, which help define specific patterns.

Some common metacharacters are:

• . – matches any single character except a newline
• \w – matches any word character (letters, digits, and underscores)
• \d – matches any digit (0-9)
• \s – matches any whitespace character (including spaces, tabs, and newlines)

It’s important to remember that these metacharacters must be preceded by a backslash to represent their special meanings.

Special Characters

There are several special characters in regex that have specific meanings:

• * – matches zero or more occurrences of the preceding character
• + – matches one or more occurrences of the preceding character
• ? – matches zero or one occurrences of the preceding character
• {n} – matches exactly n occurrences of the preceding character
• {n,m} – matches a minimum of n and a maximum of m occurrences of the preceding character

These special characters can be combined with metacharacters and other characters to create complex patterns. My experience with Python’s regex capturing groups has been incredibly useful in extracting and manipulating specific parts of text data. Once you get the hang of it, you’ll find many ways to leverage these tools for your projects.

Python Regex Module

In this section, I will share my knowledge on importing the regex module and some useful common functions when working with Python regex capturing groups.

Importing the Module

Before I can use the regex module, I need to import it into my Python script. To do so, I simply add the following line of code at the beginning of my script:

import re

After importing the re module, you can start using regular expressions to perform various text searching and manipulation tasks.

Common Functions

The Python regex module has several helpful functions that make working with regular expressions easier. Some of the most commonly used functions include:

• re.compile(): Compiles a regular expression pattern into an object for later use. The pattern can then be applied to various texts using the object’s methods. Example:

pattern = re.compile(r'\d+')

• re.search(): Searches the given string for a match to the specified pattern. Returns a match object if a match is found, and None if no matches are found. Example:

result = re.search(pattern, "Hello 123 World!")

• re.findall(): Returns a list of all non-overlapping matches of the pattern in the target string. If no matches are found, an empty list is returned. Example:

result = re.findall(pattern, "My number is 555-1234, and my friend's number is 555-5678")

• re.finditer(): Returns an iterator containing match objects for all non-overlapping matches in the target string. Example:

result = re.finditer(pattern, "I have 3 cats, 2 dogs, and 1 turtle")

By using these functions, I can effectively search and manipulate text data using regular expressions. Python regex capturing groups make it even simpler to extract specific pieces of information from the text.

Capturing Groups

As I dive into Python regex, one concept that has consistently come up is capturing groups. These groups simplify the process of isolating parts of a matched string for further use. In this section, I’ll discuss creating capturing groups, referencing captured groups, and the concept of non-capturing groups. Let’s dive in!

Creating Capturing Groups

Creating a capturing group is as simple as encasing a part of a regular expression pattern in parentheses. For instance, if I have the pattern (\d+)-(\d+), there are two capturing groups: one for each set of digits.

You can see this in action using the Python regex library like this:

import re pattern = re.compile(r'(\d+)-(\d+)')
match = pattern.search('Product: 123-456')

Now, the match object contains two captured groups : one for '123' and another for '456'.

Referencing Captured Groups

After capturing groups, you might want to reference them for various operations. Using the group() method, you can obtain the values captured. You can access them by their index, where group(0) represents the entire matched string, and group(1), group(2), etc., correspond to the subsequent captured groups.

In my previous example, I can quickly access the captured groups like this:

first_group = match.group(1) # '123'
second_group = match.group(2) # '456'

Pretty straightforward, right?

Non-Capturing Groups

Sometimes, you want a group only for the regex pattern, without capturing its content. This can be achieved by using non-capturing groups. To create one, add ?: following the opening parenthesis: (?:...).

Here’s an example:

import re pattern = re.compile(r'(?:ID: )(\d+)')
match = pattern.search('User ID: 789')

In this case, the 'ID: ' portion is within a non-capturing group, and only the digits afterwards are captured. Now, if I reference the captured group, I only get the user ID:

user_id = match.group(1) # '789'

And there you have it! I hope this illustrates the basics of Python regex capturing groups, including creating captures, referencing them, and when to use non-capturing groups. Happy regex-ing!

Advanced Techniques

In this section, I will discuss some advanced techniques for working with capturing groups in Python regular expressions. These techniques, such as named capturing groups and conditional matching, can make your regex patterns more powerful and easier to read. Let’s dive in!

Named Capturing Groups

Named capturing groups allow you to assign a name to a specific capturing group. This makes your regex patterns more readable and easier to understand. In Python, you can define a named capturing group using the following syntax: (?P<name>...), where “name” is the desired name for the group, and “…” represents the pattern you want to capture.

For example, let’s say I want to extract dates with the format “MM/DD/YYYY“. Here’s how I can use named capturing groups:

import re pattern = r"(?P<month>\d\d)/(?P<day>\d\d)/(?P<year>\d\d\d\d)"
date_string = "12/25/2020"
match = re.search(pattern, date_string) if match: print('Month:', match.group('month')) print('Day:', match.group('day')) print('Year:', match.group('year'))

This will output:

Month: 12
Day: 25
Year: 2020

As you can see, using named capturing groups made our regex pattern more readable, and accessing the captured groups is much simpler.

Conditional Matching

Conditional matching in regex allows you to match different patterns based on the existence of specific capturing groups. In Python, you can use the following syntax for conditional matching: (?(id)yes|no), where “id” is the identifier for a capturing group, and “yes” and “no” are the patterns to match if the specified group exists, respectively.

For example, let’s say I want to find all occurrences of the word "color" or "colour" in a text. I can use conditional matching to achieve this:

import re pattern = r"col(ou)?r(?(1)u|o)r"
text = "I like the color red. My favourite colour is blue."
matches = re.findall(pattern, text) for match in matches: print(match[0])

This will output:

o
ou

Here, we used conditional matching to identify both the American and British spellings of "color/colour" and print the captured group responsible for the difference.

I hope you find these advanced techniques useful in your Python regex adventures. Good luck exploring even more regex possibilities!

Practical Examples

In this section, I’ll demonstrate a couple of practical examples using Python regex capturing groups, focusing on email validation and URL parsing.

Email Validation

Validating email addresses is a common task in many applications. Using capturing groups, I can create a regex pattern to match and validate email addresses. Let’s get started. First, here’s the regex pattern:

'^([a-zA-Z0-9._%+-]+)@([a-zA-Z0-9.-]+)\.([a-zA-Z]{2,})$'

In this pattern, I’ve used several capturing groups:

• The first group ([a-zA-Z0-9._%+-]+) captures the username part of the email address. It includes letters, numbers, and some special characters.
• The second group ([a-zA-Z0-9.-]+) captures the domain name, which consists of letters, numbers, and some special characters.
• The third group ([a-zA-Z]{2,}) captures the top-level domain, consisting of at least two letters.

Now, let’s use this regex pattern in a Python function to validate an email address:

import re def validate_email(email): pattern = r'^([a-zA-Z0-9._%+-]+)@([a-zA-Z0-9.-]+)\.([a-zA-Z]{2,})$' if re.match(pattern, email): # I match the input email against the pattern return True else: return False

URL Parsing

In this example, I’ll show you how to use capturing groups to parse and extract components from a URL. Let’s start with the regex pattern:

'^(https?)://([^\s/:]+)(:\d+)?(/)?(.*)?$'

In this pattern, I’ve used several capturing groups:

• The first group (https?) captures the protocol (http or https).
• The second group ([^\s/:]+) captures the domain name.
• The third group (:\d+)? captures the optional port number.
• The fourth group (/)? captures the optional slash after the domain and port.
• The fifth group (.*)? captures the remaining URL path, if any.

Now, let’s create a Python function to extract the components from a URL:

import re def parse_url(url): pattern = r'^(https?)://([^\s/:]+)(:\d+)?(/)?(.*)?$' match = re.match(pattern, url) # I match the input URL against the pattern if match: return { 'protocol': match.group(1), 'domain': match.group(2), 'port': match.group(3), 'slash': match.group(4), 'path': match.group(5) } else: return None

With this parse_url function, I can now extract and analyze various components of a URL.

Python f-strings, available since Python 3.6, offer a concise way to embed expressions in string literals using curly braces {}. They improve readability and performance over older methods like %-formatting and str.format(). To use f-strings, prefix the string with “f” or “F” and enclose expressions within braces: f"My name is {name} and I am {age} years old."

In recent years, Python has seen the development and adoption of several new features, one of which is f-strings. Also known as formatted string literals, f-strings were introduced in Python 3.6 via PEP 498. They have quickly become popular, as they offer a simple and straightforward syntax for embedding expressions inside strings, with the output being evaluated at runtime.

As a Python developer, I’ve found f-strings to be immensely useful for improving the readability and efficiency of my code. Rather than using more cumbersome methods like concatenation or the str.format() function, f-strings allow me to inline expressions directly within a string by using curly braces {}, significantly simplifying parts of the code.

In my experience, f-strings have not only enhanced the overall development process but have also contributed to the increased adoption of Python as a go-to programming language for various applications. This powerful string formatting feature makes Python even more appealing to both beginners and experienced programmers alike.

But before we start, allow me to show you another beautiful birds pic:

Understanding Python F-Strings

As a Python enthusiast, I’m always excited to share the features that make Python so elegant and easy to use. One such feature is Python f-strings, introduced in Python 3.6 . They are a fantastic way to format strings and greatly enhance the readability of your code.

Basics of F-Strings

F-strings, also known as formatted string literals, are a more modern and efficient way of formatting strings compared to traditional methods like str.format(). The best part about using f-strings is their simplicity – you just need to use an “f” or “F” in front of your string, followed by the expressions enclosed in curly braces {} that you want to embed within the string .

For instance, let’s compare the old and new ways of formatting strings:

name = "Alice"
age = 30 # Using str.format()
formatted_old = "{} is {} years old".format(name, age) # Using f-string
formatted_new = f"{name} is {age} years old"

As you can see, f-strings not only make the code more readable but also more concise. Trust me, once you start using f-strings, there’s no going back!

F-Strings Syntax

F-strings follow a very straightforward syntax that makes them effortless to use in daily coding tasks. Let me show you how it works:

• Begin your string with an “f” or “F“: f"..." or F"...".
• Embed expressions in curly braces {}: f"My name is {name}".
• You can also use expressions inside the curly braces, like f"3 + 5 = {3 + 5}".
• Format specifiers can be added after the expression using ! and : symbols, such as f"pi rounded to 2 decimals: {3.14159:.2f}".

Here’s a quick example that demonstrates how powerful and versatile f-strings can be:

name = "Bob"
score = 87.345 result = f"{name}, your score is {score:.1f}%, which is {'good' if score >= 80 else 'average'}!"

In this example, I’ve used an f-string to embed the person’s name, round their score to one decimal place, and conditionally evaluate their performance based on the score – all within a single line of code!

F-strings truly are a game-changer in Python, and I hope you find them as useful and efficient as I do. Happy coding!

Advantages of Using F-Strings

Readability, performance and scalability, coding efficiency, and versatility are four main advantages of using f-strings! Before I show you the advanced capabilities of f-strings, let’s quickly discuss each of those advantages next!

F-String Advantage 1: Readability

Firstly, I’ve found that using f-strings in Python makes my code more readable.

F-strings allow me to embed expressions directly into the string itself, using curly braces {}. This not only makes it easier to understand the code at a glance, but also reduces the chance of errors due to the smooth flow of the text.

Furthermore, f-strings aren’t cluttered with special characters, unlike other formatting methods (Towards Dev).

F-String Advantage 2: Performance

Another advantage of using f-strings is their scalability and performance improvements.

Since they were introduced in Python 3.6, f-strings have proven to be faster than other string formatting methods because the expressions within the curly braces are evaluated at runtime (Towards Data Science). This can be crucial, especially in large-scale projects where every millisecond counts .

F-String Advantage 3: Coding Efficiency

Not only that, but f-strings can help improve my coding efficiency.

Their concise syntax saves me from dealing with overly verbose formatting code, which can become unwieldy in complex situations. With f-strings, it’s easier for me to grasp what the code is supposed to do without getting lost in a sea of parentheses and method calls.

F-String Advantage 4: Versatility

Finally, f-strings offer more versatility when it comes to mixing variable types.

In one line of code, I can include strings, integers, and even complex data structures such as dictionaries or lists. This flexibility makes f-strings invaluable for developers who work with diverse datasets and need to output multi-layered information in a streamlined format .

F-Strings Expressions

In this section, I’m going to discuss f-strings expressions, which are a powerful aspect of Python f-strings. They allow you to embed variables and even perform operations within the string. Let’s dive into the details.

Variables and Literals

One of the most useful features of f-strings is the ability to include variables directly within the string. To do this, simply include the variable inside curly braces {} within the f-string.

For example:

name = "Alice"
age = 25
my_string = f"Hello, my name is {name} and I am {age} years old."
print(my_string)

This code would output:

Hello, my name is Alice and I am 25 years old.

You can see how the variables are easily replaced within the f-string without the need for concatenation or complex formatting methods.

You can also include literals or expressions, like:

my_string = f"Hello, my name is {'Alice'} and I am {25 + 1} years old."
print(my_string)

This would output:

Hello, my name is Alice and I am 26 years old.

Escape Characters

Sometimes, you might need to include curly braces in your f-string. Since they’re used for expressions, you’ll need to escape them by doubling them up. This is quite simple, just use two curly braces, like {{ or }}:

my_string = f"Showing amount in dollars: {{100}}"
print(my_string)

This would output:

Showing amount in dollars: {100}

With this knowledge, I can now create more readable and concise f-strings in my Python code. Whether it’s injecting variables, using literals, or handling escape characters, f-strings make my life as a coder much easier.

Formatting Text with F-Strings

In this section, I’ll discuss how to format text using Python f-strings, a powerful feature introduced in Python 3.6. I’ll cover three key sub-topics: padding and alignment, formatting numbers, and date and time formatting. Let’s dive in!

Padding and Alignment

To pad and align text using f-strings, I’ll use the curly braces {} as placeholders within the f-string. To illustrate this, I’ll align a string to the left, right, and center. For left alignment, I can use the '<' sign, for right alignment the '>' sign, and for center alignment, I’ll use the '^' sign.

Here’s how it’s done:

name = "John"
print(f"{name:<10}") # Left align
print(f"{name:>10}") # Right align
print(f"{name:^10}") # Center align

These examples display the text 'John' with a width of 10 characters, aligned to the left, right, and center, respectively.

Formatting Numbers

Formatting numbers is a breeze with f-strings. I can specify the precision, add a thousand separator, and perform other formatting tasks.

For example, to round a number to two decimal places, I’ll use the ‘f‘ type and set the precision like so:

number = 3.14159265
formatted_number = f"{number:.2f}"
print(formatted_number) # Output: 3.14

Adding a thousand separator is simple using the ‘,‘ option:

big_number = 1234567
formatted_big_number = f"{big_number:,}"
print(formatted_big_number) # Output: 1,234,567

Neat, right?

Date and Time Formatting

Python f-strings also make it easy to format date and time values. To do this, I’ll import the datetime module and format a datetime object like so:

from datetime import datetime current_time = datetime.now()
formatted_time = f"{current_time:%Y-%m-%d %H:%M:%S}"
print(formatted_time) # Output: e.g., 2023-04-06 13:31:46

In this example, I used the format codes %Y, %m, %d, %H, %M, and %S to display the year, month, day, hour, minute, and second, respectively.

I hope these examples clarified how to use f-strings for formatting text, numbers, and dates in Python.

F-Strings and Security

When it comes to string formatting in Python, f-strings have some notable advantages, especially regarding security. I’ve found that f-strings are safer than other formatting options, like str.format() or %-formatting. Using f-strings helps protect code from potential security risks related to untrusted data in format strings.

When I use str.format() or %-formatting, it’s crucial to ensure that format strings are either static or sanitized. Thanks to f-strings, this concern is significantly reduced, making my code less prone to input-based vulnerabilities.

To illustrate this, let’s consider a simple example:

# Using %-formatting:
print("Hello, %s!" % user_input) # Using str.format():
print("Hello, {}!".format(user_input)) # Using f-strings:
print(f"Hello, {user_input}!")

In all three cases, the user_input variable is being inserted into the string. While %-formatting and str.format() can lead to unwanted behavior if the user_input contains unexpected format specifiers, f-strings don’t suffer from this issue. This makes them a more secure choice for handling user-provided data.

However, it’s essential to note that even though f-strings are generally more secure, I shouldn’t let my guard down completely. It’s always good to follow best practices for validating and sanitizing user input to ensure that my Python code remains secure and resistant to potential attacks.

Comparing F-Strings to Other Formatting Methods

As a Python programmer, I’ve come across several ways to format strings. In this section, I will dive into a comparison of f-strings with two other popular formatting methods: percent-style string formatting and the str.format() method.

Percent-Style String Formatting

Before f-strings and the str.format() method, percent-style formatting was commonly used. It resembled the way strings are formatted in C, using the percent symbol (%) as a placeholder. For example, to insert a variable into a string, I would write:

name = "Alice"
output = "Hello, %s!" % name
print(output) # Output: Hello, Alice!

While this method is easy to use for simple formatting, it can become difficult to read and maintain when dealing with multiple variables or complex string compositions.

Str.format() Method

Introduced in Python 2.6, the str.format() method offered a more readable approach compared to percent-style formatting. Instead of using the percent symbol, I would include placeholders in the form of curly braces {}:

name = "Alice"
output = "Hello, {}!".format(name)
print(output) # Output: Hello, Alice!

The str.format() method allows me to utilize advanced formatting options, such as specifying field widths and alignment. However, even though it is more powerful and flexible than percent-style formatting, it can still become cumbersome for complex strings.

Now, let’s see how f-strings compare to these two methods. With f-strings, introduced in Python 3.6, I can include expressions within the curly braces, and the syntax is more concise:

name = "Alice"
output = f"Hello, {name}!"
print(output) # Output: Hello, Alice!

Not only do f-strings make my code more readable, they also tend to be faster than the other two formatting methods!

As a Python programmer who values readability and performance, I find that f-strings are the way to go when it comes to string formatting. While percent-style and str.format() methods still have their place in older codebases, f-strings offer a cleaner and more efficient solution for my string formatting needs.

In this article, I will discuss a popular and efficient way to work with structured data in Python using DataFrames.

A DataFrame is a two-dimensional, size-mutable, and heterogeneous tabular data structure with labeled axes (rows and columns). It can be thought of as a table or a spreadsheet with rows and columns that can hold a variety of data types.

One common challenge is converting a Python list of dictionaries into a DataFrame.

To create a DataFrame from a Python list of dicts, you can use the pandas.DataFrame(list_of_dicts) constructor.

Here’s a minimal example:

import pandas as pd
list_of_dicts = [{'key1': 'value1', 'key2': 'value2'}, {'key1': 'value3', 'key2': 'value4'}]
df = pd.DataFrame(list_of_dicts) 

With this simple code, you can transform your list of dictionaries directly into a pandas DataFrame, giving you a clean and structured dataset to work with.

A similar problem is discussed in this Finxter blog post:

Recommended: How to Convert List of Lists to a Pandas Dataframe

Converting Python List of Dicts to DataFrame

Let’s go through various methods and techniques, including using the DataFrame constructor, handling missing data, and assigning column names and indexes.

Using DataFrame Constructor

The simplest way to convert a list of dictionaries to a DataFrame is by using the pandas DataFrame constructor. You can do this in just one line of code:

import pandas as pd
data = [{'a': 1, 'b': 2}, {'a': 3, 'b': 4}]
df = pd.DataFrame(data)

Now, df is a DataFrame with the contents of the list of dictionaries. Easy peasy!

Handling Missing Data

When your list of dictionaries contains missing keys or values, pandas automatically fills in the gaps with NaN values. Let’s see an example:

data = [{'a': 1, 'b': 2}, {'a': 3, 'c': 4}]
df = pd.DataFrame(data)

The resulting DataFrame will have NaN values in the missing spots:

 a b c
0 1 2.0 NaN
1 3 NaN 4.0

No need to manually handle missing data!

Assigning Column Names and Indexes

You may want to assign custom column names or indexes when creating the DataFrame. To do this, use the columns and index parameters:

column_names = ['col_1', 'col_2', 'col_3']
index_names = ['row_1', 'row_2']
df = pd.DataFrame(data, columns=column_names, index=index_names)

This will create a DataFrame with the specified column names and index labels:

 col_1 col_2 col_3
row_1 1.0 2.0 NaN
row_2 3.0 NaN 4.0

Working with the Resulting DataFrame

Once you’ve converted your Python list of dictionaries into a pandas DataFrame, you can work with the data in a more structured and efficient way.

In this section, I will discuss three common operations you may want to perform with a DataFrame:

• filtering and selecting data,
• sorting and grouping data, and
• applying functions and calculations.

Let’s dive into each of these sub-sections!

Filtering and Selecting Data

Working with data in a DataFrame allows you to easily filter and select specific data using various techniques. To select specific columns, you can use either DataFrame column names or the loc and iloc methods.

Recommended: Pandas loc() and iloc() – A Simple Guide with Video

For example, if you need to select columns A and B from your DataFrame, you can use the following approach:

selected_columns = df[['A', 'B']]

If you want to filter rows based on certain conditions, you can use boolean indexing:

filtered_data = df[(df['A'] > 5) & (df['B'] < 10)]

This will return all the rows where column A contains values greater than 5 and column B contains values less than 10.

Sorting and Grouping Data

Sorting your DataFrame can make it easier to analyze and visualize the data. You can sort the data using the sort_values method, specifying the column(s) to sort by and the sorting order:

sorted_data = df.sort_values(by=['A'], ascending=True)

Grouping data is also a powerful operation to perform statistical analysis or data aggregation. You can use the groupby method to group the data by a specific column:

grouped_data = df.groupby(['A']).sum()

In this case, I’m grouping the data by column A and aggregating the values using the sum function. These operations can help you better understand patterns and trends in your data.

Applying Functions and Calculations

DataFrames allow you to easily apply functions and calculations on your data. You can use the apply and applymap methods to apply functions to columns, rows, or individual cells.

For example, if you want to calculate the square of each value in column A, you can use the apply method:

df['A_squared'] = df['A'].apply(lambda x: x**2)

Alternatively, if you need to apply a function to all cells in the DataFrame, you can use the applymap method:

df_cleaned = df.applymap(lambda x: x.strip() if isinstance(x, str) else x)

In this example, I’m using applymap to strip all strings in the DataFrame, removing any unnecessary whitespace. Utilizing these methods will make your data processing and analysis tasks more efficient and easier to manage.

To keep improving your data science skills, make sure you know what you’re going yourself into:

Recommended: Data Scientist – Income and Opportunity

Many businesses will agree that it takes a lot more time, money, and resources to get new customers than to keep existing ones. Hence, they are very much interested in knowing how many existing customers are leaving their business. This is known as churn.

Churn tells business owners how many customers are no longer using their products and services. It is also the rate at which an amount of money is lost as a result of customers or employers leaving the company. The churn rate gives companies an idea of business performance. If the churn rate is higher than the growth rate, it means that the business is not growing.

There are many reasons offered to explain customer churn. These include poor customer satisfaction, finance issues, customers not feeling appreciated, and customers’ need for a change. Understandably, companies have no absolute control over churn. But they can work to reduce to the barest minimum churn rate as regards the ones they have greater control.

As data scientists, your role is to assist these companies by building a churn model tailored to the company’s goals and expectations to predict customer churn. Due to the lack of data available to meet a company’s specific needs, it becomes challenging for data scientists to design an effective churn model.

However, we will make do with sample data for a fictional telecommunication company. You know, it is membership-based businesses performing subscription-based services that are mostly affected by customer churn. This data sourced by the IBM Developer Platform is available on my GitHub page.

The dataset has 7043 rows and 21 columns which comprise 17 categorical features, 3 numerical features, and the prediction feature. Check my GitHub page for more information about the dataset.

Data Preprocessing

This step will be taken to make the data suitable for machine learning. We will start by getting an overview of the dataset.

import pandas as pd
df = pd.read_csv('churn.csv') # get the shape of the dataset
df.shape
(7043, 21) # print the columns
df.columns
Index('customerID', 'gender', 'SeniorCitizen', 'Partner', 'Dependents', 'tenure', 'PhoneService', 'MultipleLines', 'InternetService', 'OnlineSecurity', 'OnlineBackup', 'DeviceProtection', 'TechSupport', 'StreamingTV', 'StreamingMovies', 'Contract', 'PaperlessBilling', 'PaymentMethod', 'MonthlyCharges', 'TotalCharges', 'Churn'], dtype='object') # check for missing values df.isna().sum() '''
customerID 0
gender 0
SeniorCitizen 0
Partner 0
Dependents 0
tenure 0
PhoneService 0
MultipleLines 0
InternetService 0
OnlineSecurity 0
OnlineBackup 0
DeviceProtection 0
TechSupport 0
StreamingTV 0
StreamingMovies 0
Contract 0
PaperlessBilling 0
PaymentMethod 0
MonthlyCharges 0
TotalCharges 0
Churn 0
dtype: int64 ''' #check for duplicates
df.customerID.nunique()
7043

Next, we drop the customerID column which was just there for identification purposes.

df.drop(['customerID'], axis=1, inplace=True)

The axis=1 means the columns. The inplace parameter is directly applied to the dataset.

If you take a look at the dataset using the head() method, you will notice that many features including the target feature have rows with values of Yes and No. We will transform them to 0 and 1 using LabelEncoder from the Scikit-learn library. We will also do the same with columns that have more than two categories.

from sklearn.preprocessing import LabelEncoder label_encoder = LabelEncoder()
obj = (df.dtypes == 'object')
for col in list(obj[obj].index): df[col] = label_encoder.fit_transform(df[col])

Model Building

It’s now time to train our data using Machine Learning algorithms. As we don’t know which model will perform well on our dataset, we will first test using different models.

from sklearn.model_selection import train_test_split
from sklearn.preprocessing import StandardScaler
from sklearn.metrics import accuracy_score
from sklearn.linear_model import LogisticRegression
from sklearn.tree import DecisionTreeClassifier
from sklearn.neighbors import KNeighborsClassifier
from sklearn.discriminant_analysis import LinearDiscriminantAnalysis
from sklearn.naive_bayes import GaussianNB
from sklearn.svm import SVC
from sklearn.ensemble import AdaBoostClassifier
from sklearn.ensemble import RandomForestClassifier
from sklearn.ensemble import ExtraTreesClassifier
from sklearn.ensemble import GradientBoostingClassifier
from xgboost import XGBClassifier X = df.drop([‘Churn’], axis=1)
Y = df.Churn X_train, X_test Y_train, Y_test = train_test_split(X, Y, test_size=0.2, random_state=7) models = [LogisticRegression(), RandomForestClassifier(),AdaBoostClassifier(), SVC(), DecisionTreeClassifier(), KNeighborsClassifier(), GaussianNB(), ExtraTreesClassifier(), LinearDiscriminantAnalysis(), GradientBoostingClassifier(), ] scaler = StandardScaler()
rescaledX = scaler.fit_transform(x_train) for model in models: model.fit(rescaledX, Y_train.values) preds = model.predict(X_test.values) results = accuracy_score(Y_test, preds) print(f'{results}') '''
0.2753726046841732
0.7388218594748048

The results show that XGBoost performed better than the other models in this dataset. Therefore, we will use XGBoost as our Machine Learning algorithm to predict customer churn.

Tuning XGBoost

The XGBoost algorithm achieved a 74% accuracy score. Can it do better? Let’s try tuning the model using learning curves. To understand what we meant by the learning curve, please read this article.

models = [LogisticRegression(), RandomForestClassifier(),AdaBoostClassifier(), SVC(), DecisionTreeClassifier(), KNeighborsClassifier(), GaussianNB(), ExtraTreesClassifier(), LinearDiscriminantAnalysis(), GradientBoostingClassifier(), ] scaler = StandardScaler()
rescaledX = scaler.fit_transform(x_train) for model in models: model.fit(rescaledX, Y_train.values) preds = model.predict(X_test.values) results = accuracy_score(Y_test, preds) print(f'{results}')

The results show that XGBoost performed better than the other models in this dataset. Therefore, we will use XGBoost as our Machine Learning algorithm to predict customer churn.

Tuning XGBoost

The XGBoost algorithm achieved a 74% accuracy score. Can it do better? Let’s try tuning the model using learning curves. To understand what we meant by the learning curve, please read this article.

# define the model
model = XGBClassifier() # define the datasets to evaluate each iteration
evalset = [(X_train, Y_train), (X_test, Y_test)] # fit the model
model.fit(X_train, Y_train, eval_metric='logloss', eval_set=evalset) # evaluate performance
preds = model.predict(X_test)
score = accuracy_score(y_test, preds) print(f'Accuracy: {round(score*100, 1)}%')
# Accuracy: 77.9%

Wow, the model has improved with 77.9% accuracy score. Can it still do better? Let’s increase the number of iterations from 100 (default) to 200 and reduce the eta hyperparameter to 0.05 (default is 0.3) to slow down the learning rate.

model = XGBClassifier(n_estimators=200, eta=0.05) # fit the model
model.fit(X_train, Y_train, eval_metric='logloss', eval_set=evalset) preds = model.predict(x_test) score = accuracy_score(y_test,preds) print(f'Accuracy: {round(score*100, 1)}%')
# Accuracy: 78.6%

This is the extent we can go. Of course, we can go on tuning the model to achieve a higher score. An accuracy score of 78.6% is not bad.

Create a new folder and save the following to a file named model.py.

#Import libraries
import pandas as pd
from xgboost import XGBClassifier
import pickle
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import LabelEncoder df = pd.read_csv('churn.csv') # Drop customerID
df.drop(['customerID'], axis=1, inplace=True) # Convert to int datatype label_encoder = LabelEncoder()
obj = (df.dtypes == ‘object’)
for col in list(obj[obj].index): df[col] = label_encoder.fit_transform(df[col]) X = df.drop(['Churn'], axis=1)
Y = df.Churn # splitting the dataset
X_train, X_test, Y_train, Y_test = train_test_split(X, Y, test_size=0.2, random_state=7) model = XGBClassifier(n_estimators=200, eta=0.05) # define the datasets to evaluate each iteration
evalset = [(X_train, Y_train), (X_test, Y_test)] # fit the model
model.fit(X_train, Y_train, eval_metric='logloss', eval_set=evalset) # saving the trained model
pickle.dump(model, open('lg_model.pkl', 'wb'))

Notice we save the trained model as a pickle object to be used later. We want the model to be running on Streamlit local server. So, we will create a Streamlit application for this. Create other files called app.py and predict.py in your current folder. Check my GitHub page to see the full content of the files.

Please remember to manually run the model.py to generate the pickle file as I won’t be pushing it to GitHub. After running the model.py file, the accuracy was 80.4% showing the model learned the data very well.

Conclusion

In this tutorial, we created a customer churn prediction app to help businesses deal with some of the challenges facing them. We use the XGBoost model to train the data and generate the model. There are many things we didn’t do. Data visualization, feature engineering, and dealing with imbalance classification are some of them.

You may wish to try them out and see if they can improve the model’s performance. Unfortunately, I wasn’t able to deploy the app because I couldn’t push the heavy pickle file to GitHub. Try pushing yours and then, you deploy it on Streamlit Cloud. Alright, enjoy your day.

I recently started a new website and to rank up in the search engines I hired an SEO expert. He suggested several activities out of which one was building lots of backlinks. We agreed on the budget and the timeframe in which he delivers 200 links in a month. These links are a mix of social bookmarks, profile pages, and guest articles. After he delivers the Links, I have to verify the work done and give feedback. The process of checking a URL containing the backlink is as follows –

• Open a URL from a list of URLs in the sheet
• Search for my “mydomain.com” in the source code or click on the visible link pointing to my domain
• In the sheet, mark it as LINK FOUND or LINK NOT FOUND

Only if it was this easy.

The link-building project will go on for several months. He will be building several hundred links so I must have some tool to do the checking for me. So, I came up with the idea of asking ChatGPT to give me a code in Python. Here is my prompt:

Prompt

Give me a Python code that scrapes all given URLs and looks for any link that contains "mydomain.com" and prints out the URL and the link it found

ChatGPT reply:

import requests
from bs4 import BeautifulSoup # list of URLs to scrape
urls = ['https://example.com', 'https://example.net', 'https://example.org'] # loop through each URL
for url in urls: # send a request to the URL response = requests.get(url) # parse the HTML content with BeautifulSoup soup = BeautifulSoup(response.content, 'html.parser') # find all links in the page links = soup.find_all('a') # loop through each link for link in links: # check if the link contains "mydomain.com" if 'partymap.in' in link.get('href', ''): # print the URL and link found print(f"{url} - {link.get('href')}")

Choosing Google Colab as Web-Based Python Interface

Now I have to run this code in a web interface. The interface should have an input box and an output box.

I find Google Collab to be the best option to do this in a quick, easy, and time-efficient manner. But I need the code to read the list of URLs from an input widget box. So I returned to ChatGPT and defined my environment along with many improvisations. There were several trials and errors.

Here are some of the prompts

Improvisation Prompt 1:

Also add the following Display domains that are duplicate
Display unique list of domains in which the string was not found

Improvisation Prompt 2:

I got this error ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:992)

Improvisation Prompt 3:

Check for Redirection, if the URL redirects, print "E:REDIRECTED" and skip iteration

Improvisation Prompt 4:

I got a mod_security error in request.get, how can I fix it

Improvisation Prompt 5:

Add a try catch block around request and beautiful soup

Improvisation Prompt 6:

If there are no Links found, print "E:ZERO LINKS" and skip iteration

Improvisation Prompt 7:

The list of URLs will come from a google collab input box can you make the change

And there were many more prompts to achieve the final results. But, since I am a Python coder, I could exit the back and forth with ChatGPT and change the code my way.

ERROR/STATUS CODES

Explanation of error codes is as follows

Errors found in URL given in the sheet

• UNRESOLVED – The URL in the sheet is malformed
• DUPLICATE DOMAIN – There are multiple URLs from the same domain
• REDIRECTED – The URL redirected to another URL, if this happens ask the SEO analyst to post the final URL in the sheet

Errors found in Links found in the source code of the URL

• FOUND – Our domain backlink was found
• NOT FOUND – Our domain backlink was not found
• BAD LINK – Our domain backlink was not found
• ZERO LINKS – No links were found in the source code

I begin each error code with ‘E:’ to easily identify them in sheet for conditional formatting process.

So here is the final code:

The Code

This goes in the first code cell of Google Colab

Recommended: 7 Effective Prompting Tricks for ChatGPT

Playing with any large language model (LLM), such as GPT-4, is fascinating. 

But it doesn’t give you an accurate understanding of where AGI is heading because one isolated snapshot provides limited information. You can gain more insight into the growth and dynamicity of LLMs by comparing two subsequent snapshots.

Roughly speaking, it’s less interesting to see where baby AGI is and more interesting to look at how it evolves. 

To gain more insight on this, Emily has just contributed another interesting Finxter blog article:

Recommended: [Blog] 10 High-IQ Things GPT-4 Can Do That GPT-3.5 Can’t

Check it out. It’s a solid read!

It’s fascinating to observe how the concept of transformers introduced in the 2017 paper “Attention is all you need” has scaled so remarkably well. 

In essence, the significant advancements made in AI over the past four years have mostly come from scaling up the transformer approach to an incredible magnitude. The concept of GPT (Generative Pre-trained Transformers) has remained largely unchanged for around six years.

They just threw more data and more hardware on the same algorithm. This was possible due to the higher amount of scalability and degree of parallelization unlocked by the transformer idea.

From the paper (highlights by me):

“In this work we propose the Transformer, a model architecture eschewing recurrence and instead relying entirely on an attention mechanism to draw global dependencies between input and output. The Transformer allows for significantly more parallelization … the Transformer is the first transduction model relying entirely on self-attention to compute representations of its input and output without using sequence-aligned RNNs or convolution.”

My main takeaway from comparing GPT-3.5 to GPT-4 is that the limits of performance improvements are not yet reached by simply throwing more and more data and hardware on these models. And when the performance (=IQ) of transformer models ultimately converges — probably at a super-human IQ level — we’ll still be able to change and improve on the underlying abstractions to eke out additional IQ.

Likely, transformers will not remain the last and best-performing model for all future AI research. We have tried only the tip of the iceberg on what scale these models go. I wouldn’t be surprised if the data sets and computational power of future GPT models increased by 1,000,000x.

Truly an exciting time to be alive!  

I’m scared and fascinated at the same time. It’s so new and so dangerous. Ubiquitous disruption of the work marketplace is already happening fast. I’d estimate that in our economy, we already have north of one billion “zombie jobs”, i.e., job descriptions that could be fully automated with ChatGPT and code. I know of closed-loop AI models under government review that classify cancer with almost zero error rate. Medical doctors with lower accuracy are still doing the classification – but for how long? 

A new era is starting. When we went from 99% to 1% farmers, we accomplished a massive leap of free work energy that led to an explosion of collective intelligence. The same is happening now: 99% of the jobs will be gone sooner than we expect. A massive amount of free energy will catapult humanity forward like we’ve never experienced in the history of humanity.

Buckle up for the ride. I’ll be here to help you navigate the waters until my job will be disrupted too and AGI will help you more effectively than I ever could. 

The future is bright!

This was part of my free newsletter on technology and exponential technologies. You can join us by downloading our cheat sheets here:

In this article, I will cover accessing multiple matches of a regex group in Python.

Regular expressions (regex) are a powerful tool for text processing and pattern matching, making it easier to work with strings. When working with regular expressions in Python, we often need to access multiple matches of a single regex group. This can be particularly useful when parsing large amounts of text or extracting specific information from a string.

To access multiple matches of a regex group in Python, you can use the re.finditer() or the re.findall() method.

• The re.finditer() method finds all matches and returns an iterator yielding match objects that match the regex pattern. Next, you can iterate over each match object and extract its value.
• The re.findall() method returns all matches in a list, which can be a more convenient option if you want to work with lists directly.

Problem Formulation: Given a regex pattern and a text string, how can you access multiple matches of a regex group in Python?

Understanding Regex in Python

In this section, I’ll introduce you to the basics of regular expressions and how we can work with them in Python using the ‘re‘ module. So, buckle up, and let’s get started!

Basics of Regular Expressions

Regular expressions are sequences of characters that define a search pattern. These patterns can match strings or perform various operations like search, replace, and split into text data.

Some common regex elements include:

• Literals: Regular characters like 'a', 'b', or '1' that match themselves.
• Metacharacters: Special characters like '.', '*', or '+' that have a special meaning in regex.
• Character classes: A set of characters enclosed in square brackets (e.g., '[a-z]' or '[0-9]').
• Quantifiers: Specify how many times an element should repeat (e.g., '{3}', '{2,5}', or '?').

These elements can be combined to create complex search patterns. For example, the pattern '\d{3}-\d{2}-\d{4}' would match a string like '123-45-6789'.

Remember, practice makes perfect, and the more you work with regex, the more powerful your text processing skills will become.

The Python ‘re’ Module

Python comes with a built-in module called ‘re‘ that makes it easy to work with regular expressions. To start using regex in Python, simply import the ‘re‘ module like this:

import re

Once imported, the ‘re‘ module provides several useful functions for working with regex, such as:

Function	Description
re.match()	Checks if a regex pattern matches at the beginning of a string.
re.search()	Searches for a regex pattern in a string and returns a match object if found.
re.findall()	Returns all non-overlapping matches of a regex pattern in a string as a list.
re.finditer()	Returns an iterator yielding match objects for all non-overlapping matches of a regex pattern in a string.
re.sub()	Replaces all occurrences of a regex pattern in a string with a specified substitution.

By using these functions provided by the ‘re‘ module, we can harness the full power of regular expressions in our Python programs. So, let’s dive in and start matching!

Working with Regex Groups

When working with regular expressions in Python, it’s common to encounter situations where we need to access multiple matches of a regex group. In this section, I’ll guide you through defining and capturing regex groups, creating a powerful tool to manipulate text data.

Defining Groups

First, let’s talk about how to define groups within a regular expression. To create a group, simply enclose the part of the pattern you want to capture in parentheses. For example, if I want to match and capture a sequence of uppercase letters, I would use the pattern ([A-Z]+). The parentheses tell Python that everything inside should be treated as a single group.

Now, let’s say I want to find multiple groups of uppercase letters, separated by commas. In this case, I can use the pattern ([A-Z]+),?([A-Z]+)?. With this pattern, I’m telling Python to look for one or two groups of uppercase letters, with an optional comma in between.

Capturing Groups

To access the matches of the defined groups, Python provides a few helpful functions in its re module. One such function is findall(), which returns a list of all non-overlapping matches in the string.

For example, using our previous pattern:

import re
pattern = r'([A-Z]+),?([A-Z]+)?'
text = "HELLO,WORLD,HOW,AREYOU"
matches = re.findall(pattern, text)
print(matches)

This code would return the following result:

[('HELLO', 'WORLD'), ('HOW', ''), ('ARE', 'YOU')]

Notice how it returns a list of tuples, with each tuple containing the matches for the specified groups.

Another useful function is finditer(), which returns an iterator yielding Match objects matching the regex pattern. To extract the group values, simply call the group() method on the Match object, specifying the index of the group we’re interested in.

An example:

import re
pattern = r'([A-Z]+),?([A-Z]+)?'
text = "HELLO,WORLD,HOW,AREYOU" for match in re.finditer(pattern, text): print("Group 1:", match.group(1)) print("Group 2:", match.group(2))

This code would output the following:

Group 1: HELLO
Group 2: WORLD
Group 1: HOW
Group 2:
Group 1: ARE
Group 2: YOU

As you can see, using regex groups in Python offers a flexible and efficient way to deal with pattern matching and text manipulation. I hope this helps you on your journey to becoming a regex master!

Accessing Multiple Matches

As a Python user, sometimes I need to find and capture multiple matches of a regex group in a string. This can seem tricky, but there are two convenient functions to make this task a lot easier: finditer and findall.

Using ‘finditer’ Function

I often use the finditer function when I want to access multiple matches within a group. It finds all matches and returns an iterator, yielding match objects that correspond with the regex pattern .

To extract the values from the match objects, I simply need to iterate through each object :

import re pattern = re.compile(r'your_pattern')
matches = pattern.finditer(your_string) for match in matches: print(match.group())

This useful method allows me to get all the matches without any hassle. You can find more about this method in PYnative’s tutorial on Python regex capturing groups.

Using ‘findall’ Function

Another option I consider when searching for multiple matches in a group is the findall function. It returns a list containing all matches’ strings. Unlike finditer, findall doesn’t return match objects, so the result is directly usable as a list:

import re pattern = re.compile(r'your_pattern')
all_matches = pattern.findall(your_string) print(all_matches)

This method provides me with a simple way to access all the matches as strings in a list.

Practical Examples

Let’s dive into some hands-on examples of how to access multiple matches of a regex group in Python. These examples will demonstrate how versatile and powerful regular expressions can be when it comes to text processing.

Extracting Email Addresses

Suppose I want to extract all email addresses from a given text. Here’s how I’d do it using Python regex:

import re text = "Contact me at [email protected] and my friend at [email protected]"
pattern = r'([\w\.-]+)@([\w\.-]+)\.(\w+)'
matches = re.findall(pattern, text) for match in matches: email = f"{match[0]}@{match[1]}.{match[2]}" print(f"Found email: {email}")

This code snippet extracts email addresses by using a regex pattern that has three capturing groups. The re.findall() function returns a list of tuples, where each tuple contains the text matched by each group. I then reconstruct email addresses from the extracted text using string formatting.

Finding Repeated Words

Now, let’s say I want to find all repeated words in a text. Here’s how I can achieve this with Python regex:

import re text = "I saw the cat and the cat was sleeping near the the door"
pattern = r'\b(\w+)\b\s+\1\b'
matches = re.findall(pattern, text, re.IGNORECASE) for match in matches: print(f"Found repeated word: {match}")

Output:

Found repeated word: the

In this example, I use a regex pattern with a single capturing group to match words (using the \b word boundary anchor). The \1 syntax refers to the text matched by the first group, allowing us to find consecutive occurrences of the same word. The re.IGNORECASE flag ensures case-insensitive matching. So, no repeated word can escape my Python regex magic!

Conclusion

In this article, I discussed how to access multiple matches of a regex group in Python. I found that using the finditer() method is a powerful way to achieve this goal. By leveraging this method, I can easily iterate through all match objects and extract the values I need.

Along the way, I learned that finditer() returns an iterator yielding match objects, which allows for greater flexibility when working with regular expressions in Python. I can efficiently process these match objects and extract important information for further manipulation and analysis.

Recommended: How I Created a High-Performance Extensible ChatGPT Chatbot with Python (Easy)

No, ChatGPT really doesn’t help with this (yet…) but it did help me write the code snippet explanation (which I attached after each code output).

In my example, we will take a special route in Budapest, using one of the easiest to use library, gmplot.

We can create our maps directly in HTML code using its many methods.
To access some functions, you need a Google Maps API key.

I used Python’s built-in zip function to create the Lat – Lon coordinates, you can learn more about zip here:

Recommended: Python zip() Built-in Function

We can work with the following methods of the GoogleMapPlotter object, which I will describe in detail:

GoogleMapPlotter

• from_geocode(location, zoom=10, apikey='')
• draw(path_file)
• get()
• geocode(location, apikey='')
• text(lat, lon, text, color='red')
• marker(lat, lon, color='#FF0000', title=None, precision=6, label=None, **kwargs)
• enable_marker_dropping(color, **kwargs)
• directions
• scatter
• circle
• plot
• heatmap
• ground_overlay
• polygon
• grid

Let’s go through the functions using “code snippets”:

Find a location by name (from_geocode)

With the geocode method of the GoogleMapPlotter object, we can display a given address and its neighbourhood on the map.

Parameters of the method: location (str), zoom (int), apikey (str)

After creating your map, you have two options, either save the HTML file (.draw()) or store it as a string (with .get()). I use the .draw() method, where the only parameter is the file to create and its path.

import gmplot
apikey = '' # (your API key here)
gmap = gmplot.GoogleMapPlotter.from_geocode('Budapest', apikey=apikey)
gmap.draw("budapest_map.html")

Result:

The code imports the gmplot library, which is a Python wrapper for the Google Maps API. It then creates a new GoogleMapPlotter object named gmap for the location “Budapest” using the from_geocode() method. This method uses the Google Maps API to retrieve the latitude and longitude of the location, which is necessary to display the map.

Finally, the draw() method is called on the gmap object to generate and save the map as an HTML file named budapest_map.html.

Coordinates of a location (geocode)

If you want to know the coordinates of a location, use .geocode(). As an input parameter, pass the name (str) of the place you are looking for and your API key. This returns a tuple of the lat/long coordinates of the given location (float, float).

import gmplot
apikey = '' # (your API key here)
location = gmplot.GoogleMapPlotter.geocode('Budapest, Hungary', apikey=apikey)
print(location)

Result:

(47.497912, 19.040235)

The code calls the geocode() method on the GoogleMapPlotter object to obtain the latitude and longitude of a location specified as a string. In this case, the location is “Budapest, Hungary”. The apikey parameter is also passed to this method to authenticate the Google Maps API.

Text on your map (text)

If you want to place custom text on your map, you can do it with .text(), using the text label’s Latitude and Longitude parameter.

It is possible to color the text with the color=str parameter, which can be the color name ('black'), hexadecimal ('#000000'), or matplotlib-like ('k').

import gmplot
apikey = ' ' # (your API key here)
gmap = gmplot.GoogleMapPlotter(47.519350864380385, 19.010462124312387, zoom = 17, apikey=apikey)
finxter_text = ['f', 'i', 'n', 'x', 't', 'e', 'r']
colors = ['limegreen', 'cyan', 'gold','orange', 'limegreen', 'cyan', 'orange']
j = 0
lat = 47.529266431577625
lng = 19.00500303401821
for i in finxter_text: gmap.text(lat, lng, i, color = colors[j]) j += 1 lng += 0.001

Result:

Drop marker (marker)

Show markers. The required parameters are, of course, the Latitude and Longitude coordinates (float, float), and additional optional parameters can be used to customize the markers:

• color (str) which can be the name of the color ('black'), hexadecimal ('#000000'), or matplotlib-like ('k')
• title (str) : Hover-over title of the marker.
• precision (int) : Number of digits after the decimal to round to for lat/long values. Defaults to 6.
• label (str) : Label displayed on the marker.
• info_window (str) : HTML content to be displayed in a pop-up info window.
• draggable (bool) : Whether or not the marker is draggable.

import gmplot
apikey = ' ' # (your API key here)
gmap.marker(47.51503432784726, 19.005350430919034, label = 'finxter', info_window = "<a href='https://finxter.com/'>The finxter Academy</a>", draggable = False)

gmap.enable_marker_dropping(color=’black’)

gmap.enable_marker_dropping() allows markers to be dropped onto the map when clicked. Clicking on a dropped marker will delete it.

Note: Calling this function multiple times will just overwrite the existing dropped marker settings.

Parameters:

• color str: Color of the markers to be dropped.
• title str: Hover-over title of the markers to be dropped.
• label str: Label displayed on the markers to be dropped.
• draggable bool: Whether or not the markers to be dropped are draggable.

Result:

The code adds a marker to the Google Maps plot. The marker is placed at the latitude and longitude coordinates (47.51503432784726, 19.005350430919034) and is labeled 'finxter'.

The info_window parameter sets the information displayed when the user clicks on the marker. In this case, it is a link to the Finxter Academy website.

The draggable parameter is set to False, meaning that the user cannot move the marker.

The fourth line enables marker dropping, meaning the user can add new markers to the plot by clicking on the map.

The final line saves the plot to an HTML file named marker.html.

Route planning (directions)

Using the Directions API, you can display route planning between any points. The origin and destination coordinates are given as parameters (float, float). Optionally, the waypoints as list of tuples and the travel_mode as str can also be specified. The travel modes are:

• DRIVING (Default) indicates standard driving directions using the road network.
• BICYCLING requests bicycling directions via bicycle paths & preferred streets.
• TRANSIT requests directions via public transit routes.
• WALKING requests walking directions via pedestrian paths & sidewalks.

Sometimes it is useful to draw a circle. In addition to specifying the center lat, lng, and radius of the circle, you can also to specify the following:

• edge_alpha/ea float: Opacity of the circle’s edge, ranging from 0 to 1. Defaults to 1.0.
• edge_width/ew int: Width of the circle’s edge, in pixels. Defaults to 1.
• face_alpha/alpha float: Opacity of the circle’s face, ranging from 0 to 1. Defaults to 0.5.
• color/c/face_color/fc str: Color of the circle’s face. Can be hex (“#00FFFF”), named (“cyan”), or matplotlib-like (“c”). Defaults to black.
• color/c/edge_color/ec

import gmplot
apikey = ' ' # (your API key here)
gmap = gmplot.GoogleMapPlotter(47.519350864380385, 19.010462124312387, zoom = 14, apikey=apikey)
gmap.circle(47.51894874729591, 18.99426698678921, 200, face_alpha = 0.4, ec = 'cyan', fc='cyan')

Result:

The fourth line uses the circle() method to add a circle to the plot.

The circle() method takes the latitude and longitude coordinates of the center of the circle as its first two arguments, followed by the radius of the circle in meters.

The face_alpha parameter specifies the transparency of the circle fill, while the ec and fc parameters specify the color of the circle edge and fill, respectively.

Polyline (plot)

A polyline is a line composed of one or more sections. If we want to display such a line on our map, we use the plot method. In addition to the usual lats [float], lons [float] parameters, you can specify the following optional parameters:

• color/c/edge_color/ec str : Color of the polyline. Can be hex (“#00FFFF”), named (‘cyan’), or matplotlib-like (‘c’). Defaults to black.
• alpha/edge_alpha/ea float: Opacity of the polyline, ranging from 0 to 1. Defaults to 1.0.
• edge_width/ew int: Width of the polyline, in pixels. Defaults to 1.
• precision int: Number of digits after the decimal to round to for lat/lng values. Defaults to 6.

import gmplot

gmap.plot(*f, edge_width = 7, color = 'limegreen')
gmap.draw('poly.html')

Result:

f = zip(*[(47.513285942712805, 18.994089961008104), (47.51453956566773, 18.991150259891935), (47.51573518971617, 18.992276787691928), (47.51453956566773, 18.991150259891935), (47.51417000363217, 18.992040753295736), (47.515372882275294, 18.99316728109573)])

This line creates a list of latitude-longitude pairs that define the vertices of a polygon. The zip(*[...]) function is used to transpose the list so that each pair of latitude-longitude values becomes a separate tuple.

gmap.plot(*f, edge_width = 7, color = 'limegreen')

This line plots the polygon on the Google Map. The plot() function takes the *f argument, which is unpacked as separate arguments, representing the latitude and longitude values of the polygon vertices. The edge_width parameter sets the width of the polygon edges in pixels and the color parameter sets the color of the edges.

Create heatmap (heatmap)

Plot a heatmap.

Parameters:

• Latitudes [float],
• Longitudes [float]

Optional Parameters:

• radius [int]: Radius of influence for each data point, in pixels. Defaults to 10.
• gradient [(int, int, int, float)]: Color gradient of the heatmap as a list of RGBA colors. The color order defines the gradient moving towards the center of a point.
• opacity [float]: Opacity of the heatmap, ranging from 0 to 1. Defaults to 0.6.
• max_intensity [int]: Maximum intensity of the heatmap. Defaults to 1.
• dissipating [bool]: True to dissipate the heatmap on zooming, False to disable dissipation.
• precision [int]: Number of digits after the decimal to round to for lat/lng values. Defaults to 6.
• weights [float]: List of weights corresponding to each data point. Each point has a weight of 1 by default. Specifying a weight of N is equivalent to plotting the same point N times.

)
gmap.draw('heatmap.html')

Result:

First, a list of tuples called letters is created. Each tuple contains two values representing latitude and longitude coordinates of a point on the map.

Then, an instance of the GoogleMapPlotter class is created with a specified center point, zoom level, and an API key.

Next, the heatmap method of the GoogleMapPlotter object is called, passing in the letters list as positional arguments, along with other parameters.

The radius parameter determines the radius of each data point’s influence on the heatmap, while the weights parameter determines the intensity of each data point’s contribution to the heatmap.

The gradient parameter is a list of tuples representing the color gradient of the heatmap, with each tuple containing four values representing red, green, blue, and alpha values.

Finally, the opacity parameter determines the transparency of the heatmap.

Picture above the map (ground_overlay)

Overlay an image from a given URL onto the map.

Parameters:

• url [str]: URL of image to overlay.
• bounds [dict]: Image bounds, as a dict of the form {'north':, 'south':, 'east':, 'west':}.

Optional Parameters:

• opacity [float]: Opacity of the overlay, ranging from 0 to 1. Defaults to 1.0.

gmap.ground_overlay(url, bounds, opacity=0.3)
gmap.draw('overlay.html')

Result:

The variable url contains the URL of an image that will be used as the ground overlay. The bounds dictionary defines the north, south, east, and west coordinates of the image on the map.

Finally, the ground_overlay method is called on the GoogleMapPlotter object, passing the URL and bounds variables as arguments. The opacity parameter is set to 0.3 to make the overlay partially transparent. The resulting map is saved to a file called overlay.html using the draw method.

Plot a Polygon

gmap.draw('poligon.html')

Result:

Defines a set of coordinates for a polygon named finxter_in_Budapest.

Calls the gmap.polygon() method with the *finxter_in_Budapest argument to draw the polygon on the map. The face_color, face_alpha, edge_color, and edge_width parameters define the appearance of the polygon.

Saves the map as an HTML file named 'poligon.html' using the gmap.draw() method.

Display grid (grid)

The parameters are used to specify the grid start and end points and the width and length of the grid.

(lat_start, lat_end, lat_increment, lng_start, lng_end, lng_increment)

import gmplot
apikey = ' ' # (your API key here)
gmap = gmplot.GoogleMapPlotter(47.519350864380385, 19.010462124312387, zoom = 14, apikey=apikey)
gmap.grid(47.50, 47.53, 0.0025, 19.0, 19.05, 0.0025)
gmap.draw('grid.html')

Result:

This code generates a Google Map centered at latitude 47.519350864380385 and longitude 19.010462124312387, with a zoom level of 14. It then adds a grid to the map with vertical lines spaced 0.0025 degrees apart between longitude 19.0 and 19.05, and horizontal lines spaced 0.0025 degrees apart between latitude 47.50 and 47.53. Finally, it saves the resulting map with the grid to an HTML file named "grid.html".

Conclusion

Congratulations, now you’ve learned how to draw almost anything on Google Maps with a few lines of code. While gmplot is a powerful library, it has some limitations (e.g., I can’t figure out how to change the color of the path), so maybe other modules like geopandas are a good place to learn more.

A Few Final Words on gmplot

gmplot is a Python library that allows the user to plot data on Google Maps. It provides a simple interface to create various types of maps, including scatterplots, heatmaps, ground overlays, and polygons.

With gmplot, the user can add markers, lines, and shapes to the map, customize colors, labels, and other properties, and export the map to a static HTML file.

The library uses the Google Maps API and requires an API key to be able to use it. gmplot is a useful tool for visualizing geospatial data and creating interactive maps for data exploration and analysis.
