It's not an iterator. It's an iterable. So every time you call iter() on it - which is done implicitly by the starting of the 'for' loop - you get a completely new iterator which will step through the whole range object. *A range object is not an iterator.* ChrisA -- https://mail.python.org/mailman/listinfo/python-list
