They are never the same unless you only add one item to the list. append() will only increase the length of a list by 1. la = [1,2] lb = [3, 4, 5] la += lb print la lc = [1,2] lc.append(lb) print lc --output:-- [1, 2, 3, 4, 5] [1, 2, [3, 4, 5]] print la[2] print lc[2] --output:-- 3 [3, 4, 5] -- http://mail.python.org/mailman/listinfo/python-list
