Steven D'Aprano <steve+pyt...@pearwood.info> added the comment:
Your metaclass.__new__ method returns None instead of the new class. The rule for calling __init__ is: - if the constructor __new__ returns an instance of the type, then call the initializer __init__ - otherwise, don't call __init__ at all. https://docs.python.org/3/reference/datamodel.html#object.__new__ Since your __new__ accidentally returns None, the __init__ is not called. If you change the line to say return super().__new__(cls, *args, **kwargs) you will see that __init__ is called. (And discover the bugs in your init method :-) ---------- nosy: +steven.daprano resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36178> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
