Not related to your actual question, but note: > if len(result) == 0:
empty lists test as False, so this can just be > if not result: and > result[len(result)-1] -= 128 you can index lists with negative ints, backwards from the end of the list, so this can be > result[-1] -= 128 Those are two of my favorite things about python. :-) Peace, ~Simon -- http://mail.python.org/mailman/listinfo/python-list
