In python 2.4, you could achieve this by saying: elements.sort(key=lambda x: x[1][1]) In earlier versions of python, you can do: elements.sort(lambda x, y: cmp(x[1][1], y[1][1])) (but this is less efficient than key= in 2.4) There's also the decorate-sort-undecorate idiom: dec = [(x[1][1], x) for x in elements] dec.sort() elements = [x[1] for x in dec] -- John. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
