Stuck on list override code challenge

I am not sure if I am going about this the right way...I am still trying to acclimate on where to plug and play the appropriate values. If I could have someone look at my code and provide me feedback, I would greatly appreciate it. Thanks in advance.

frustration.py
class Liar(list):
    def __len__(self, count):
        fake = list.__len__(self, count)
        if fake == count:
            return count - 2

The "__len__" method doesn't take an argument, and a better way to call a method in a parent class is by using "super()".
