from abc import ABC


class A:
    def __init_subclass__(self):
        pass


class B(ABC, A, name="name"):
    pass


After initialising class B, this exception occurs, because multiple "name" arguments where provided:

Traceback (most recent call last):

    class B(ABC, A, name="name"):
TypeError: __new__() got multiple values for argument 'name'
