The last step is asking you to double the value before returning it. Since Double inherits from int you can use any of int's methods as well as operators (which are basically a special set of methods in Python), you can use the * operator to multiply by 2 like this:

class Double(int):
    def __new__(*args, **kwargs):
        self = int.__new__(*args, **kwargs)
        return self * 2
