Calling a parent method from outside the child

I have a bunch of class objects which all inherit from a base class. Some of them override a method (save) and do stuff. For this particular use case I want to temporarily not allow the child save method to be used (if it exists) but rather force the use of the parent save method.

class BaseClass(object):
    def save(self, *args, **kwargs):
        print("Base Called")

class Foo(BaseClass):
    def save(self, *args, **kwargs):
        # do_stuff
        print("Foo called")
        return super(Foo, self).save(*args, **kwargs)

obj = Foo()

How can I call obj parent save from outside the child such that it prints "Base Called"?

You can call methods from an objects parent with super()

super(type(obj), obj).save()

When I run this:

class BaseClass(object):
    def save(self, *args, **kwargs):
        print("Base Called")

class Foo(BaseClass):
    def save(self, *args, **kwargs):
        # do_stuff
        print("Foo called")
        return super(Foo, self).save(*args, **kwargs)

obj = Foo()
super(type(obj), obj).save()

The output:

Base Called
