Hi Python experts! Please explain this behavior: >>> nn=3*[[]] >>> nn [[], [], []] >>> mm=[[],[],[]] >>> mm [[], [], []]
Up till now, 'mm' and 'nn' look the same, right? Nope! >>> mm[1].append(17) >>> mm [[], [17], []] >>> nn[1].append(17) >>> nn [[17], [17], [17]] ??? Python 2.5 Win XP Thanks! -- http://mail.python.org/mailman/listinfo/python-list
