How to Get Started with Beautiful Soup

Embarking on your web scraping journey with Beautiful Soup is straightforward. Follow these steps to set up and begin extracting data:

Installation

To install Beautiful Soup along with the requests library, open your terminal and enter the following command:

pip install requests beautifulsoup4

Import Libraries

Next, in your Python script, import the necessary libraries:

import requests
from bs4 import BeautifulSoup

Make an HTTP Request

Utilize the requests library to fetch the content of a webpage. Here’s how to do it:

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

Parse the Content

Create a Beautiful Soup object to parse the HTML:

soup = BeautifulSoup(response.content, 'html.parser')

Navigate and Extract Data

Now that you have the page parsed, you can use methods like find() and find_all() to extract specific elements. Here’s an example to find all the links (<a> tags) on the page:

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