Object-Oriented Python Frustration Challenge
I am having a bit of trouble getting this bit of code to work. The objective is to override the len() method to work on a list subclass, Liar, Any tips are appreciated
class Liar(list): def __len__(self): return super().__len__(self) + 3

So close! You have one small error in this line:
return super().__len__(self) + 3
When you call the
__len__ method on the superclass you don't pass
self is the argument that you define on all regular methods in a class but Python supplies
self automatically when you call it.
Hope that helps,
