python program to read a url and extract its meta keyword and meta description

read_meta_data.py

from bs4 import BeautifulSoup
import requests


def main():
    #r = requests.get('http://www.aurionpro.com/')
    r = requests.get('http://www.sourcebits.com/')
    soup = BeautifulSoup(r.content, "html")

    title = soup.title.string
    print 'TITLE IS :', title

    meta = soup.find_all('meta')

    for tag in meta:
        if 'name' in tag.attrs.keys() and tag.attrs['name'].strip().lower() in ['description', 'keywords']:
            print 'NAME    :',tag.attrs['name'].lower()
            print 'CONTENT :',tag.attrs['content']

if __name__ == '__main__':
    main()

Thanks for the code, how do we add a for loop to the code if we have multiple URLs?
