items = zip(*sorted(zip(values, items)))[1] To better understand this please note that a = [1, 2] b = [3, 4] zip(*zip(a, b)) == a, b or, in other words, zip(*argument) is the inverse of an argument created by zip (under the assumption the a and b have equal length) Diez -- http://mail.python.org/mailman/listinfo/python-list
