Getting attribute's value using BeautifulSoup

Question

I\'m writing a python script which will extract the script locations after parsing from a webpage. Lets say there are two scenarios :

Answer 1

This should work, you just filter to find all the script tags, then determine if they have a 'src' attribute. If they do then the URL to the javascript is contained in the src attribute, otherwise we assume the javascript is in the tag

#!/usr/bin/python

import requests 
from bs4 import BeautifulSoup

# Test HTML which has both cases
html = '  '

soup = BeautifulSoup(html)

# Find all script tags 
for n in soup.find_all('script'):

    # Check if the src attribute exists, and if it does grab the source URL
    if 'src' in n.attrs:
        javascript = n['src']

    # Otherwise assume that the javascript is contained within the tags
    else:
        javascript = n.text

    print javascript

This output of this is
