Question

E.g. is this possible?

class Foo(object):
    class Meta:
        pass

class Bar(Foo):
    def __init__(self):
        # remove the Meta class here?
        super(Bar, self).__init__()

Answer 1

You cannot remove class attributes from an inherited base class; you can only mask them, by setting an instance variable with the same name:

class Bar(Foo):
    def __init__(self):
        self.Meta = None  # Set a new instance variable with the same name
        super(Bar, self).__init__()

Your own class could of course also override it with a class variable:

class Bar(Foo):
    Meta = None

    def __init__(self):
        # Meta is None for *all* instances of Bar.
        super(Bar, self).__init__()
