The first one is better because the second one has a bug. ;-) Because of the way the second one uses values.index, it assumes there is a unique mapping between items and values. When a duplicate integer appears in values, the second solution returns the wrong answer. -Jeff _______________________________________________ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
