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.
class Inventory: def __init__(self): self.slots =  def add_item(self, item): self.slots.append(item) class SortedInventory(Inventory): super().add_item(item)
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!
