Python Web Scraping

Introduction

Web scraping is a technique used to extract data from websites. In this tutorial, we will learn how to perform web scraping using Python.

Requirements

• Python installed on your system
• Basic knowledge of Python programming
• Internet connection

Installing Required Libraries

We will use the requests and BeautifulSoup libraries for web scraping. Install them using pip:

pip install requests beautifulsoup4

Fetching a Web Page

First, we need to fetch the content of a web page. We can do this using the requests library:

import requests

url = 'https://example.com'
response = requests.get(url)
print(response.text)

Parsing HTML Content

Next, we will parse the HTML content using BeautifulSoup:

from bs4 import BeautifulSoup

soup = BeautifulSoup(response.text, 'html.parser')
print(soup.prettify())

Extracting Data

We can now extract specific data from the HTML. For example, to extract all the links:

links = soup.find_all('a')
for link in links:
    print(link.get('href'))

Conclusion

In this tutorial, we learned the basics of web scraping using Python. We covered fetching a web page, parsing HTML content, and extracting data.
