Joseph Perez <joperez@hotmail.fr> added the comment: That's why it's not an interpreter issue but a lack in the official documentation where the signature is documented. I quote https://docs.python.org/3/library/functions.html#type:
class type(object) class type(name, bases, dict)
The second line should be "class type(name, bases, dict, **kwargs)". (I've mentioned Pycharm and Mypy, but i think it's a kind of side-effect of the incomplete official documentation on which is based their typeshed) In fact, I've raised this issue because I've found myself needing to instantiate a class using `type` and kwargs, and I've not found in the documentation an example of it. ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue41644> _______________________________________
