Re: Is this a bug in Python or something I do not understand.

L1 is a list of three different lists, although each list holds the same values. L2 is a list of three references to the same list (the '*' operator doesn't do a deep copy). So when you modify any of the referenced lists, you modify all of them. Try this: >>> q = [1, 1, 1] >>> r = [q, q, q] >>>
