Overriding a parent's method in my subclass

Directions state that I should override the add_item method. I assume this means in the new SortedInventory subclass that I created. How exactly do I override a specific method?

inventory.py
class Inventory:
    def __init__(self):
        self.slots = []

    def add_item(self, item):
        self.slots.append(item)

class SortedInventory(Inventory):
    pass

Anytime you create a method with the same name as one in the parent class, it overrides the one in the parent class.

If desired, you can call the one in the parent class by prefixing it with "super().".

class Inventory:
    def __init__(self):
        self.slots = []

    def add_item(self, item):
        self.slots.append(item)

class SortedInventory(Inventory):

   ## I am assuming you have to sort items in this class
    def add_item(self, item):
       self.slots.append(item).sort().
