If A has no duplicate elements, you could create a hash mapping A's elements to their respective precedences, then provide a sort criterion that accessed the hash. Alternatively, you could do something like this: from operator import itemgetter result = map(itemgetter(0), sorted(zip(A, B), key=itemgetter(1))) -- http://mail.python.org/mailman/listinfo/python-list
