None is an 'value' which is intended to denote the absence of any 'value' *other than None*. > I would, FWIW, only make such a distinction in the context of a > computer program... Clearly in mathematics and elsewhere, zero is the > lack of a value (it is the value of nothingness). I would like to have a word with your maths teacher! There are plenty of uses for 0, most of which are unrelated to 'nothingess'. E.g. 0 is *greater* than -1 so it must be something. -- Arnaud -- http://mail.python.org/mailman/listinfo/python-list
