I don't know if it's kludgy, but I do prefer to set counters in the for statement whenever I can. If I were using 2.4, I might try writing something like: for i,(animal,zoo) in enumerate((animal,zoo) for animal in zoo for color in animal): pass or maybe break it down a little for clarity: aciter = ((animal,zoo) for animal in zoo for color in animal) for i,(animal,zoo) in enumerate(aciter): pass But even the clear version isn't as nearly clear and straightforward as the nested fors with the counter. I wouldn't forsake that clarity just so it isn't "kludgy". Carl Banks -- http://mail.python.org/mailman/listinfo/python-list
