Hello all, I didn't found more appropriate news group for this question, please let me know if there is ng with regular expression as its main topic
I am trying to construct a case where a greedy and non greedy operation produce different result. I dont see the difference between 'a??b' and 'a?b' As far I understand is that ? will first try to match a (it's greedy) and only if it fails then it step back and lets a unmatched. The other doesn't match a at first, only if the pattern fails to match it steps back and match a. But don't they do eventually the same thing? Can someone provide an example where 2 patterns yield different results. Regards, Daniel -- http://mail.python.org/mailman/listinfo/python-list
