Hello, I finally found the solution of the challenge. Nevertheless I am a bit confused by one thing. When we call the super() function, why don't we include the argument self?
Why do we call it like
super().add_item(item)
instead of
super().add_item(self, item)
I intuitively feel that since super() represents a generic parent class object it's like executable code, so the self shouldn't be there. But I am not 100% sure of it.
Any logical explanation?

Treehouse Moderator 68,457 PointsThe add_item() in the super().add_item() is like any other called method: self is never included in the call.
This is the same case as if a parent class had a method that was not overridden. You would also not use self in calling this parent method.
Post back if you need more help. Good luck!!!
