[issue40304] Classes created using type() don't need to explicitly inherit from object
New submission from Борис Верховский <boris.verk@gmail.com>: As far as I can tell, passing `(object,)` and `()` as the `bases` parameter to the 3-argument version of type() produces the same result, because classes inherit from `object` in Python 3:
type('X', (object,), dict(a=1)).__bases__ (<class 'object'>,) type('X', (), dict(a=1)).__bases__ (<class 'object'>,)
I just want to make sure I'm not missing something and update the documentation of `type()` to reflect that. ---------- assignee: docs@python components: Documentation messages: 366613 nosy: boris, docs@python priority: normal pull_requests: 18902 severity: normal status: open title: Classes created using type() don't need to explicitly inherit from object type: enhancement versions: Python 3.9 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue40304> _______________________________________
