I have no idea whats going on -- overridding __new__

Kenneth is talking about ovverridding magic methods and i dont really know what this whole video is talking about. The quiz is asking me to override new. I dont even know what to ask...

class Double(int):
    def __new__(**args, **kwargs):
        super().__new__(**args, **kwargs)
        return __new__(**args, **kwargs)

Hey Andy McDonald !

You are fairly close with the code you currently have. There are just a few things to change.

class Double(int):
    def __new__(**args, **kwargs):
        super().__new__(**args, **kwargs)            # this line can be removed
        return __new__(**args, **kwargs)

First, *args should only have 1 asterisk in front of them. Otherwise the python interpreter is reading it as if it has keywords. Second, we only want to return a created instance of int that sets the value of __new__ to the passed in *args and **kwargs. To create an instance, you can put int. in front of __new__(*args, **kwargs) when you return it.

I hope this helps. Don't hesitate to reach back out if you are still stuck :)
