Create a new class named Liar that inherits from list. Override the len method so that it aways returns an incorrect number for the length. Inside of your len method use super() to call list's len method and return a modified version of the length. You won't need any arguments.
For example, if a list has two items in it, the Liar class could return a five. It should never return the correct length.

Create a new class named Liar that inherits from list.
class Liar(list):
Override the len method so that it aways returns an incorrect number for the length.
So here you define a magic method with __len__
def __len__(self):
Inside of your len method use super() to call list's len method and return a modified version of the length. You won't need any arguments. For example, if a list has two items in it, the Liar class could return a five. This should be using super(), so the format would be
super().__len__()
It should never return the correct length. Here you have to change it so that always returns something different.
return super().__len__() + 1
Hope this helps. Good luck.

They even tell you how to implement it by "use super() to call list's len method" and then modify and return it.
