Hi George, I used Python 2.4.1, the following are the command lines. But the reslut was still False. Is there anything wrong with below codes?
>>> import itertools as it >>> def hasConsequent(aString, minConsequent): for _,group in it.groupby(aString): if len(list(group)) >= minConsequent: return True return False >>> hasConsequent("taaypiqee88adbbba", 3) False >>> Regards, Aries -- http://mail.python.org/mailman/listinfo/python-list
