We’re getting kind of pedantic here, but no, it’s not “as much as” — [] and “” create new instances of a list or string. For the purposes of this document, however, these are pretty esoteric distinctions. What the docs should make clear is that None ( and True and False ) is a singleton— None will always refer to the SAME None object. And that can be demonstrated by showing that you can’t rebind the name None. But I think it’s misleading to say that that is the same as: 42 = “something else” None is syntactical a name like any other — what’s special about is that it can’t be rebound. -CHB > > -- > Rhodri James *-* Kynesim Ltd _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
