[Python] Python type hint: Intersection of types (class implementing interface)

I have a python class defining an interface

class InterfaceFoo:
pass


some abstract class

class AbstractBar:
pass


and perhaps a concrete class

class Bar(InterfaceFoo):
pass


implementing my interface (or, if you wish, both the interfaces Interface Foo and AbstractBar).

Now in some situations, I would like to have a type hint saying »I expect an instance of a class that is derived from AbstractBar and implements InterfaceFoo«. How can I do this in Python? Of course, I could go through my code and add all possible concrete classes that are subclasses of AbstractBar and implement InterfaceFoo but I think that's a very ugly solution.

def func(obj: AbstractBar implementing InterfaceFoo):
pass


This is possible in other languages, e.g. Objective-C, where you can write BaseClass<Interface>. I'm wondering, if there is an analogue in Python to this?
