Python Web Crawling Tutorial – Complete Guide

Welcome to this exciting journey into the world of web crawling! In this comprehensive tutorial, we’ll unveil Python’s incredible capabilities for web crawling and showcase how it can empower you to access and process vast quantities of data from the web.

What is Python Web Crawling?

In simple terms, web crawling refers to the automated browsing of web content – like a virtual spider – following links, and gathering data along the way. Python’s rich libraries and powerful functionalities make it an ideal language for carrying out web crawling tasks with efficiency and ease.

Web crawling is arguably one of the most sought-after skills in today’s data-driven world. As an aspiring coder, should you harness the power of Python for web crawling, you’d be able to not only retrieve and analyze massive datasets but also develop insightful applications, tools, and games!

Why Learn Python Web Crawling?

Here’s why Python web crawling should be a key part of your coding repertoire:

  • Data Access: Learning Python web crawling enables you to access and analyze vast amounts of data available on the web.
  • Job Prospects: Companies across industries are passionate about leveraging the great power of data, escalating the demand for professionals with skills in Python web crawling.
  • Diverse Applications: From developing search engines to content aggregation tools and insightful game mechanics, the possibilities are endless!

But that’s not all! Learning Python web crawling is also fun and engaging, as we’ll illustrate in the following sections with game-themed examples.

Getting Started with Python Web Crawling

Before we dive into the examples, ensure that you have Python installed. Additionally, install the ‘requests’, and ‘BeautifulSoup’ libraries, which we’ll be using. You can install them using the following commands:

pip install requests
pip install beautifulsoup4

Part 1: Making HTTP Requests in Python

The first step in Python web crawling is to send an HTTP request to the URL of the web page you want to access. Python’s ‘requests’ module provides in-built method called get() for this purpose. Here’s an illustrative example:

import requests
response = requests.get('')

Here, ‘’ is the website URL you want to access, and ‘.status_code’ returns the HTTP response status. ‘200’ signifies a successful HTTP request.

Part 2: Web Scraping with BeautifulSoup

‘BeautifulSoup’ is a Python library for parsing HTML and XML documents. We create a BeautifulSoup object and specify a parser to parse the webpage content.

from bs4 import BeautifulSoup
import requests
response = requests.get('')
soup = BeautifulSoup(response.text, 'html.parser')

‘prettify()’ method makes the HTML content more readable. Through BeautifulSoup, you can navigate and search the parse tree.

Part 3: Extracting Links

We can use ‘soup’ to extract all the links within <a> tags:

for link in soup.find_all('a'):

This will display every URL found within an <a> element on the page. If the href doesn’t exist, ‘None’ is printed.

Part 4: Scraping Text Data

You can extract all the text that is inside a paragraph <p> tag:

for data in soup.find_all('p'):

Here, ‘get_text()’ extracts all the text that is surrounded by HTML tags.

That’s it! You’re now set to begin your own web crawling adventures! Python web crawling provides a wonderful doorway into the world of Big Data, and we at Zenva can’t wait to see what you’ll create.

Part 5: Navigating the Parse Tree

One of BeautifulSoup’s strengths is its ability to navigate a parsed document’s parse tree. We can navigate the HTML tree structure using BeautifulSoup’s tag name. Here’s an example:


This prints the title tag and its content. Similarly, if you want the string inside title tag, use:


Part 6: Finding HTML Elements

Let’s suppose we want to find all instances of ‘p’ tags in the HTML document. We can do this using BeautifulSoup’s ‘.find_all()’ method.


This will return a list containing each ‘p’ tag and their text content, if any. Equally, you can search for other HTML tags by replacing ‘p’ with your desired tag.

Part 7: Finding HTML Elements with Specific Attributes

You can find HTML tags with specific attributes using BeautifulSoup. Suppose you want to find all tags which contain a specific class name:

soup.find_all('div', class_='className')

This snippet will return all ‘div’ tags that contain the class ‘className’.

Part 8: Extracting All URLs

You can use BeautifulSoup to search for ‘a’ tags and then extract their ‘href’ attribute:

for link in soup.find_all('a'):

This code snippet prints the ‘href’ attribute (or the URL of the link) of each ‘a’ tag in the HTML document.

Part 9: Finding the Parent of an HTML Element

Another great feature of BeautifulSoup is the ability to find the parent of an HTML element:

This will return the name of the tag that encloses the ‘title’ tag. With these powerful tools at your disposal, the world of Python web crawling and web scraping is your oyster!
