These are the eight best ways to check the installed version of the Python module abc:
Method 1: pip show abc
Method 2: pip list
Method 3: pip list | findstr abc
Method 4: library.__version__
Method 5: importlib.metadata.version
Method 6: conda list
Method 7: pip freeze
Method 8: pip freeze | grep abc
Before we go into these ways to check your abc version, let’s first quickly understand how versioning works in Python—you’ll be thankful to have spent a few seconds on this topic, believe me!
A Note on Python Version Numbering
Python versioning adds a unique identifier to different package versions using semantic versioning. Semantic versioning consists of three numerical units of versioning information in the format major.minor.patch.
In this tutorial, we’ll use the shorthand general version abbreviation like so:
x.y.z
Practical examples would use numerical values for x, y, and z:
1.2.3
4.1.4
1.0.0
This is shorthand for
major.minor.patch
Major releases (0.1.0 to 1.0.0) are used for the first stable release or “breaking changes”, i.e., major updates that break backward compatibility.
Minor releases (0.1.0 to 0.2.0) are used for larger bug fixes and new features that are backward compatible.
Patch releases (0.1.0 to 0.1.1) are used for smaller bug fixes that are backward compatible.
Let’s dive into the meat of this article:
Question: How to check the (major, minor, patch) version of abc in your current Python environment?
Method 1: pip show
To check which version of the Python library abc is installed, run pip show abc or pip3 show abc in your CMD/Powershell (Windows), or terminal (macOS/Linux/Ubuntu).
This will work if your pip installation is version 1.3 or higher—which is likely to hold in your case because pip 1.3 was released a decade ago in 2013!!
Here’s an example in my Windows Powershell: I’ve highlighted the line that shows that my package version is a.b.c:
In some instances, this will not work—depending on your environment. In this case, try those commands before giving up:
python -m pip show abc
python3 -m pip show abc
py -m pip show abc
pip3 show abc
Next, we’ll dive into more ways to check your abc version.
But before we move on, I’m excited to present you my new Python book Python One-Liners (Amazon Link).
If you like one-liners, you’ll LOVE the book. It’ll teach you everything there is to know about a single line of Python code. But it’s also an introduction to computer science, data science, machine learning, and algorithms. The universe in a single line of Python!
The book was released in 2020 with the world-class programming book publisher NoStarch Press (San Francisco).
To check the versions of all installed packages, use pip list and locate the version of abc in the output list of package versions sorted alphabetically.
This will work if your pip installation is version 1.3 or higher.
Here’s a simplified example for Windows Powershell, I’ve highlighted the line that shows the package version is 1.2.3:
PS C:\Users\xcent> pip list
Package Version
--------------- ---------
aaa 1.2.3
...
abc 1.2.3
...
zzz 1.2.3
In some instances, this will not work—depending on your environment. Then try those commands before giving up:
python -m pip list
python3 -m pip list
py -m pip list
pip3 list
Method 3: pip list + findstr on Windows
To check the versions of a single package on Windows, you can chain pip list with findstr abc using the CMD or Powershell command: pip3 list | findstr abc to locate the version of abc in the output list of package versions automatically.
Here’s an example for abc:
pip3 list | findstr abc 1.2.3
Method 4: Module __version__ Attribute
To check which version is installed of a given library, you can use the library.__version__ attribute after importing the library (package, module) with import library.
Here’s the code:
import my_library
print(my_library.__version__)
# x.y.z for your version output
Here’s an excerpt from the PEP 8 docs mentioning the __version__ attribute.
“PEP 8 describes the use of a module attribute called __version__ for recording “Subversion, CVS, or RCS” version strings using keyword expansion. In the PEP author’s own email archives, the earliest example of the use of an __version__ module attribute by independent module developers dates back to 1995.”
You can also use the following one-liner snippet to run this from your terminal (macOS, Linux, Ubuntu) or CMD/Powershell (Windows):
However, this method doesn’t work for all libraries, so while simple, I don’t recommend it as a general approach for that reason.
Method 5: importlib.metadata.version
The importlib.metadata library provides a general way to check the package version in your Python script via importlib.metadata.version('abc') for library abc. This returns a string representation of the specific version such as 1.2.3 depending on the concrete version in your environment.
If you have created your Python environment with Anaconda, you can use conda list to list all packages installed in your (virtual) environment. Optionally, you can add a regular expression using the syntax conda list regex to list only packages matching a certain pattern.
How to list all packages in the current environment?
conda list
How to list all packages installed into the environment 'xyz'?
conda list -n xyz
Regex: How to list all packages starting with 'abc'?
conda list '^abc'
Method 7: pip freeze
The pip freeze command without any option lists all installed Python packages in your environment in alphabetically order (ignoring UPPERCASE or lowercase). You can spot your specific package abc if it is installed in the environment.
pip freeze
Output example (depending on your concrete environment/installation):
To check the versions of a single package on Linux/Ubuntu/macOS, you can chain pip freeze with grep abc using the CMD or Powershell command: pip freeze | grep abc to programmatically locate the version of your particular package abc in the output list of package versions.
Here’s an example for abc:
pip freeze | grep abc
abc==1.2.3

Python Slice Remove First and Last Element from a List
5/5 – (1 vote)
Problem Formulation
Question: Given a Python list stored in a variable lst. How to remove the first and last elements from the list lst?
Example: The list ['Alice', 'Bob', 'Carl', 'Dave'] stored in variable lst becomes ['Bob', 'Carl'].
Method 1: Slicing List[1:-1]
To remove the first and last elements from a Python list, use the expression lst = lst[1:-1] that uses a Python feature called slicing with the syntax variable[start:stop] to iterate over a sequence starting from the start index (included) and ending in the element at stop index (excluded). If stop is a negative integer such as -i, Python takes the i-th right-most element.
To remove the first and last elements from a Python list, you can also use the slightly more complex expression lst = lst[1:len(lst)-1] that assigns the result of the slicing operation to the list and, thereby, overwrites the original longer list. We decrement the len() function result to obtain the index of the last element that is excluded from the slice.
To remove the first element of a Python list, you can use the list.pop(0) method. To remove the last element of a Python list, you can use the list.pop() method without argument. You can call both to remove the first and the last elements if the list has at least two elements.
Here’s a minimal example:
lst = ['Alice', 'Bob', 'Carl', 'Dave']
lst.pop() # remove last
lst.pop(0) # remove first
print(lst)
# ['Bob', 'Carl']
However, for a list with less than two elements, this will raise an IndexError: pop from empty list. A simple if check can make sure that the list has at least two elements—and otherwise simply override it with the empty list.
Here’s some background info in case you want to dive deeper into this approach:
The list.pop() method removes and returns the last element from an existing list. The list.pop(index) method with the optional argument index removes and returns the element at the position index.
