I'd suggest checking out copy.deepcopy. >>> a = [1, [1, 2, 3], 2] >>> b = a[:] >>> a[1][2] = 'spam' >>> b [1, [1, 2, 'spam'], 2] >>> from copy import deepcopy >>> b = deepcopy(a) >>> a[1][2] = 'deepcopy is your friend' >>> b [1, [1, 2, 'spam'], 2] Regards, Ryan Ginstrom -- http://mail.python.org/mailman/listinfo/python-list
