In python2.4, you can also use the key= keyword argument: ### def toUpper(s): return s.upper() files.sort(key=toUpper) ### This is more efficient, I believe, because the key function is only called once for each element, whereas cmp is called more than once. (we could use string.upper here instead of defining our own, but string.upper is deprecated these days...) -- John. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
