Answer 1

You can put the type in quotations to refer to it self (i.e. refer to the class via a string).

class MyClass:
    def my_func(self: 'MyClass') -> str:
        return 'Hello world!'

However, it's not necessary to use type annotation in this case as the self parameter is passed implicitly and is therefore known.
