Python Object-Oriented Python Advanced Objects Frustration

Why isn't this working

Please help with this code challenge

class Liar(list):
    def len(self):
        return super().len + 7

The purpose of super is to call a method from the parent class. So in your code, you called super().len(), so the len() is suppose to be a method? Why did you call the len() method?

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.


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().



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.

Since 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.

class Liar(list):
    def __len__(self):
        return self.super().len() + 7
what's wrong here

As 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.

Am I missing list? Also here is my updated code

class Liar(list):
    def __len__(self):
        return super().len() + 4

Your code is correct, all you have missing are 4 underscores. let me give you a hint (len).

Can someone link the super and magic methods video
