Question

How do i match from these urls:

http://foo.bar.com  
http://bar.com

foo.bar from the first link and bar from the second link using one single regex?

Answer 1

Try this:

^http://(.*)\.com$

Here’s how to use it from Python:

import re

for url in ['http://foo.bar.com', 'http://bar.com']:
    print re.match('^http://(.*)\.com$', url).group(1)

Output:

foo.bar
bar
