I love the 7-line version of the prime number generator by Tim Hochberg at the last comment of http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/117119: from itertools import count, ifilter def sieve(): seq = count(2) while True: p = seq.next() seq = ifilter(p.__rmod__, seq) yield p I suspect that it violates your second rule though :) George -- http://mail.python.org/mailman/listinfo/python-list
