What gives? Why do you think it isn't operating on x as it is? The second sort is sorting in reverse lexicographic order, which is the result you get. I'm not running Python 2.4 so I can't test this, but to get the result you want I guess you want this: py> x.sort(key=len, reverse=True) py> x ['aardvark', 'abalone', 'aerate', 'acme', 'add'] or: py> x.sort(key=len) py> x.reverse() -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
