2,442 PointsI have a problem with challenge 3, please help
This is my code
class Inventory:
def __init__(self):
self.slots = []
def add_item(self, item):
self.slots.append(item)
class SortedInventory(Inventory):
def add_item(self, item):
super().add_item(item)
super().slots.sort()
I really didn't understand the question so I try things in my way and I think I still don't know about super(), self, relations between classes. Could anyone explain these thing to me? Thank you for advance.

231,275 PointsYou're really close there, and it looks like you mostly have the right idea; but you don't need to call "super()" to access class variables. Just put "self." in front of the name:
self.slots.sort()
So use "self." for variables, and "super()" for methods.
