Let's try some more... >>> def f(x, y): ... return x*y ... >>> tmp = [1] >>> [f(x, y) for x in arr for y in [tmp[-1]] if tmp.append(f(x, y)) or >>> True][-1] 362880 OK, you've nearly convinced me that its possible but I think I still prefer reduce()! :-) Alan G. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
