Dont know why this worked... Overriding __len__

So I just looked at another question and ended up saving the super().len() to a variable and then used the +2 on the variable and it worked... I'm wondering why I had to do that.

frustration.py 
class Liar(list):
    def __len__(self):
        super().__len__()
        return __len__() + 2

You're almost there, I think you got the super() confused. Great super function explanation

This is the answer:

class Liar(list):
    def __len__(self):
        return super().__len__() + 2
