What does "override" mean in this coding challenge?

Coding challenge asks me to "override" the add_item method in my new subclass and to make sure to use super. I guess I must not understand the syntax or what override means.

Anyone know the answer/can explain it?

inventory.py 
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(self, item)

An "override" just means you are creating a method in the subclass that has the same name as a method in the parent class. So any reference to that name will be to your new one instead of the one in the parent class.

Then "super" gives you a way to access the one in the parent class anyway. Your code is almost correct, but when calling any method, you don't pass "self" explicitly as an argument. The system provides that for you.

        super().add_item(item)
