Here do this, since you called a method from the parent call list, Check if there is a method called len() in there, type this in your console.
help(list)
Scroll through it until you find something similar to your version of len() and see that the super() you called, Is it calling the right method? or is something wrong with your version of len().
SPOILER DON'T SEE SOLUTION UNTIL NECESSARY READ ABOVE
SOLUTION:
class Liar(list):
def __len__(self):
return super().__len__() + 4
I would recommend that you get a proper understanding of the super()and magic methods before continuing further in the course.

14,242 PointsSince len is supposed to be a magic method, try using it as a magic method, your code is properly structured you are just missing a magic method. Give it a little try, If you still have problems that's okay just comment for help.

20,907 PointsAs boi already mentioned len is a magic method in this challenge task and you are missing something here:
return self.super().len() + 7
Also, you do not need to use self at all.
