In a deque? Correct. But the price of that is reduced efficiency in other areas. A Python list is *not* efficient for inserting at index 0, but is compact and fast for other, more common operations. If you want a deque, you know where to find it. The list is not like that though. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
