I don't understand why this isn't working

it says task 1 is no longer passing

I don't know what I need to do

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

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

class SortedInventory(Inventory,item):
    def add_item(self, item):
        super().add_item(item)
        self.slots.sort()

Two things:

  • you have 'SortedInventory' inside the Inventory class in the add_item method. I'm not sure what this is for but the super class shouldn't have any knowledge classes that inherit from it
  • in the SortedInventory class, you have item in the list of classes that it inherits from. This is throwing an error, item isn't defined here.

Other than that, your code works:

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

    def add_item(self, item):
        self.slots.append(item)
        # removed "SortedInventory"

class SortedInventory(Inventory): # removed "item"
    def add_item(self, item):
        super().add_item(item)
        self.slots.sort()
