title: python regular expression
body: <p>whats the difference between '{m}' and '{m,n}?' in <a href="http://docs.python.org/library/re.html" rel="nofollow">http://docs.python.org/library/re.html</a> it says '{m,n}?' matches numbers in range m to n times, but it is not a greedy search. Therefore if its not a greedy search wouldn't it only match up to m no matter what?</p>
