Others have given answers involving xrange() and itertools.count(), but I thought I'd just mention that in my opinion, what you have written is pretty elegant and concise and best of all, doesn't have the same problems xrange() and itertools.count() have when then hit maxint. Not everything needs to be a one-liner or a mysterious blackbox. You could even modify your function to take start and step arguments: def integers(start=1, step=1): x = start while True: yield x x += step for odd in integers(step=2): print odd for even in integers(0, 2): print even etc. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
