Hi Kermit, Is there anything particular that you're stuck on? I think I understand your function, although I'm not sure what role z plays. Are you looking for help on how to translate the description you've given into logic suitable for programming? -- John. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
