No. In Python 2.5 there are builtins 'all' and 'any' that do exactly these. If you're using python <2.5, then you can support shortcut evaluation - there's no need to check every element once you find a false in 'all' or a true in 'any'. -- Paul Hankin -- http://mail.python.org/mailman/listinfo/python-list
