Scrape a Bookstore in 5 Steps Python [Learn Project]

5/5 – (1 vote)

Story: This series of articles assume you work in the IT Department of Mason Books. The Owner asks you to scrape the website of a competitor. He would like this information to gain insight into his pricing structure.

 Note: Before continuing, we recommend you possess, at minimum, a basic knowledge of HTML and CSS and have reviewed our articles on How to Scrape HTML tables.

What You’ll Build in This Project

Let’s navigate to Books to Scrape and review the format.

At first glance, you will notice:

• Book categories display on the left-hand side.
• There are, in total, 1,000 books listed on the website.
• Each web page shows 20 Books.
• Each price is in £ (in this instance, the UK pound).
• Each Book displays minimum details.
• To view complete details for a book, click on the image or the Book Title hyperlink. This hyperlink forwards to a page containing additional book details for the selected item (see below).
• The total number of website pages displays in the footer (Page 1 of 50).

Step 1: Install and Import Libraries for Project

Before any data manipulation can occur, three (3) new libraries will require installation.

• The Pandas library enables access to/from a DataFrame.
• The Requests library provides access to the HTTP requests in Python.
• The Beautiful Soup library enables data extraction from HTML and XML files.

To install these libraries, navigate to an IDE terminal. At the command prompt ($), execute the code below. For the terminal used in this example, the command prompt is a dollar sign ($). Your terminal prompt may be different.

$ pip install pandas

Hit the <Enter> key on the keyboard to start the installation process.

$ pip install requests

Hit the <Enter> key on the keyboard to start the installation process.

$ pip install beautifulsoup4

Hit the <Enter> key on the keyboard to start the installation process.

If the installations were successful, a message displays in the terminal indicating the same.

Add the following code to the top of each code snippet. This snippet will allow the code in this article to run error-free.

import pandas as pd

import requests

from bs4 import BeautifulSoup

import time

import urllib.request

from csv import reader, writer

• The time library is built-in with Python and does not require installation. This library contains time.sleep() and is used to set a delay between page scrapes.
• The urllib library is built-in with Python and does not require installation. This library contains urllib.request and is used to save images.
• The csv library is built-in Pandas and does not require additional installation. This library contains reader and writer methods to save data to a CSV file.

Step 2: Understand Basics and Scrape Your First Results

In this step, you’ll perform the following tasks:

• Reviewing the website to scrape.
• Understanding HTTP Status Codes.
• Connecting to the Books to Scrape website using the requests library.
• Retrieving Total Pages to Scrape
• Closing the Open Connection.

In this step, you’ll perform the following tasks:

• Configuring a page URL for scraping
• Setting a delay: time.sleep() to pause between page scrapes.
• Looping through two (2) pages for testing purposes.

Step 5: Clean and Save the Scraped Output

In this step, you’ll perform the following tasks:

• Cleaning up the scraped code.
• Saving the output to a CSV file.
