This is a minor point, but I've got the impression you're not completely aware that tuples are immutable, and what that implies. I mean that t.reverse(), assuming the same semantics as the list method, is just not possible, as it would try to alter the tuple. This is not what tuples are for, so there. Sorry if you knew this, just wanted to point out that there is a conscious difference between tuples and lists. This is of course just a half-newbie crackin wise, so forgive me ;). wildemar -- http://mail.python.org/mailman/listinfo/python-list
