I assume that's a typo and 'ibm' should be 'google'.

I think the suggestion above - (\.|,)? would work for comma, but you
could do it other ways - e.g.

   urlpat = re.compile(r'(\w+://[^>)\s]+?)[.,;]?(\s|$)') # URLs in text

to handle '.', ',' and ';', and you could extend that with more
characters, but you really need to be careful. Consider for example,
<http://www.example.com/some/page#anchor.> which could be a valid URL
ending in '.'.
