<URL: http://docs.python.org/lib/match-objects.html > says:
groups( [default])
Return a tuple containing all the subgroups of the match, from
1 up to however many groups are in the pattern. The default
argument is used for groups that did not participate in the
match; it defaults to None. (Incompatibility note: in the
original Python 1.5 release, if the tuple was one element
long, a string would be returned instead. In later versions
(from 1.5.1 on), a singleton tuple is returned in such cases.)
Since you don't have any groups in your re, groups is always going to
return (). You probably want group().
