Ah, you're right, True should take precedence, point 2 of the specs. OK, let's take advantage of the fact that None < False < True: return max(lst) This fails when lst is empty (the specs presumably imply a None should be returned then). More robust: return max(lst or [None]) Alex -- http://mail.python.org/mailman/listinfo/python-list
