Question

class Liquid(object):
    def foo(self):
        pass

    def bar(self):
        pass

class Water(Liquid):

Say, I have the two classes above, Water inherits from Liquid. Is there any way I can restrict Water from inheriting one of the parent’s methods, say bar()?

Answer 1

Sort of. But don’t do it.

class Liquid(object):
    def foo(self):
        pass

    def bar(self):
        pass

class Water(Liquid):
    def __getattribute__(self, name):
        if name == 'bar':
            raise AttributeError("'Water' object has no attribute 'bar'")

l = Liquid()
l.bar()
w = Water()
w.bar()
