Or learn to spend a bit more time digesting the helpful advice given here ... between this & the searching between two lists thread the quality of advice has been excellent. I should have used my brain a bit more before hitting send. I have a pretty good grasp of refereces vs copies, and a few seconds of time with the interactive interpreter would have clearly shown that I was dealing with references. I'm digesting all the advice ... I think I have what I need & I appreciate everyone's thoughts. I hope, at least, my questions & first drafts have been helpful for others reading along. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
