If the behaviour of * on a sequence is confusing, then isn't the following behaviour also confusing for exactly the same reason?
>>> a = [[]] >>> b = a + a >>> b [[], []] >>> b[0].append(5) >>> b [[5], [5]] And if so, shouldn't there also be a concatenation operator that performs a copy of some kind on its operands? -- Alan Bawden -- https://mail.python.org/mailman/listinfo/python-list
