How to Extract Script and CSS Files from Web Pages in Python

To extract script and CSS files from a web page in Python, you can use the BeautifulSoup library along with the requests library to send an HTTP request to the web page and parse its HTML content. Here’s an example Python code that demonstrates how to extract script and CSS URLs from a web page:

import requests
from bs4 import BeautifulSoup

url = 'https://www.example.com/page.html'

response = requests.get(url)

if response.status_code == 200:
    soup = BeautifulSoup(response.content, 'html.parser')

    # Extract script and CSS URLs
    script_urls = [script['src'] for script in soup.find_all('script', src=True)]
    css_urls = [link['href'] for link in soup.find_all('link', rel='stylesheet')]

    print('Scripts:')
    print('\n'.join(script_urls))
    print('')
    print('CSS:')
    print('\n'.join(css_urls))
else:
    print('Request failed')

In this code, we first send an HTTP GET request to the web page and use the BeautifulSoup library to parse its HTML content. We then extract the URLs of all script and CSS files by searching for the script and link tags with the appropriate attributes using find_all() method.

Note that the scripts and CSS URLs might be relative URLs, so you may need to use urllib.parse.urljoin() method to create an absolute URL from them.
