The nature of Henry's misunderstanding is a disguised version of the very common "is Python call by reference or call by value?" question that periodically crops up. I wrote a long, but I hope useful, explanation for the tu...@python.org mailing list, which I'd like to share here: http://mail.python.org/pipermail/tutor/2010-December/080505.html Constructive criticism welcome. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
