So you get the new value of > x :) Please don't do that in any code I have to read and understand. Cool little tricks have no place in good code. >>> x = range(5) >>> x.reverse() >>> x [4, 3, 2, 1, 0] does the same thing, and it a lot easier to understand. I buy my newlines in the big box at Costo, so I don't mind using a few extra ones here or there. -- http://mail.python.org/mailman/listinfo/python-list
