John,
I did "guess" but I wasn't quite sure and so I asked. OK, I did not perform a search on the docs, but that was because: 1) It is easier to learn through an interactive medium like a forum; and 2) A search in the same document you are reading takes you "off" and "adrift", and as such, is equivalant to a task-switch, because you're already reading some material from the same help file and are stuck at some point. Thanks for the help. -- http://mail.python.org/mailman/listinfo/python-list
