Error in adding method by calling super function

add an add_item method to your new SortedInventory class. It should also take an item argument. Inside your new add_item method, use super() to call add_item() and pass it item to make sure the item still gets added to the slots list.

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

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

class SortedInventory(Inventory):
    super().add_item(item)

Hi Shreya

You are missing some things in your 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):    # add an add_item method to your new SortedInventory class
        super().add_item(item)
        return self.slots    # return the slots list

Hope this helps!
