Leif's point being you *don't* want to bind a different name to each of a variable number of things - that way madness lies, as you end up creating Python statements on the fly using eval() and exec and other such dangerous and insanity-inducing tricks :-) Instead use a container structure like a list to hold them, and then use an appropriate technique to access them while they are still in the container. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://holdenweb.blogspot.com Recent Ramblings http://del.icio.us/steve.holden -- http://mail.python.org/mailman/listinfo/python-list
