How to do web scraping with Python

1 min

Web scraping with Python involves extracting data from websites. Here's a basic process to get started:

  1. Import libraries like requests and beautifulsoup4.
  2. Make a request to the website's URL and retrieve the HTML content.
  3. Parse the HTML content using beautifulsoup to extract the relevant information.
  4. Clean and structure the data as needed.
  5. Save the data in a format like CSV, Excel, or a database.

Here's an example code to extract all the titles of articles from a website using beautifulsoup:

import requests
from bs4 import BeautifulSoup

# Send a request to the website
url = ''
response = requests.get(url)
html_content = response.content

# Parse the HTML content
soup = BeautifulSoup(html_content, 'html.parser')
titles = soup.find_all('h2')

# Extract the text from each title
title_list = [title.text for title in titles]

# Print the extracted titles
for title in title_list:

This is just the basic process, and you can extend this approach to extract any type of information from websites.

In addition to requests and beautifulsoup4, there are several other popular libraries for web scraping in Python:

  1. Scrapy: A fast, high-level web crawling and web scraping framework.
  2. Selenium: A browser automation tool, often used for web scraping as well as testing websites.
  3. lxml: A library for parsing and manipulating XML and HTML documents.
  4. pandas: A library for data analysis, which can also be used to scrape and clean data from websites.
  5. mechanicalsoup: A library that makes it easy to automate form submissions, follow links, and scrape information from websites.

These libraries offer different approaches to web scraping, from high-level frameworks like Scrapy to more specialized libraries like mechanicalsoup for form submissions. Choose the best library for your specific needs and level of expertise.
