  • Is it possible to inheret a metaclass.

    I am experimenting with subclasses that all need the same metaclass as the base
    class. Is there a way to make the metaclass be inherited, so that you don't have to repeat the "metaclass = MetaClass" with every subclass.

    ?

    This is not only possible, this is the default:

    class Pardon(type): pass
    ...
    class A(metaclass=Pardon): pass
    ...
    class B(A): pass
    ...
    type(B)
    <class '__main__.Pardon'>
