Why does Python do that?
Because list.reverse() modifies a list, it doesn't create and return a new one. A common idiom for returning a reversed copy of a list is: li[::-1] You can also use the builtin "reversed" -- it doesn't return a list, but rather a reverse iterator. You can create a list from an iterator by passing it to the list() initializer, like list(reversed(li)). -- http://mail.python.org/mailman/listinfo/python-list
