I'm having a hard time overriding __len__(), any help?

I keep getting errors, am I even close?

frustration.py
class Liar(list):
    def __len__():
        super().__len__()
        return self +1

Hi there, johnahodge ! You're really close. But remember, to access self you must pass in self to the __init__.

Also, you will need to do the return on the same line with the super().__len__().

Hope these hints help! :sparkles:
