Well, re.findall(r'(\d)*', '123456') returns ['6', ''] for me, but
that's because re.findall returns the entire match, regardless of
group contents.  What you probably meant was something like
re.search(r'(\d)*', '123456').group(1), which indeed returns '6', the
contents of the last group matched.

What problem are you trying to solve?  Depending on this, the best
tool might be either findall/finditer, or search/match.
