__bases__ not working on Python 3.5?

i've implemented a small code following a book for py33 in py35. I am trying to get the super classes instances from a given subclass as follows:

class Super:
    def hello(self):
        self.data1 = 'spam'

class Sub(Super):
    def hola(self):
        self.data2 = 'eggs'

X = Sub()
X.__dict__
X.__class__
X.__bases__

However, when i excecute the X.__bases__ command i get an error:

AttributeError: 'Sub' object has no attribute '__bases__'

Could someone explain to me why is this happening and how can I (if not so) get the instances of the superclasses of a given class?

Thanks to you all :)

You can get it from the class, not the instance, see the documentation of __bases__:

class.__bases__

The tuple of base classes of a class object.

so, in short, use type(X).__bases__.
