Having Trouble on Code Challenge: Super! Task 3 of 3

I am not sure what to write inside the list.sort() method to sort the slots list. If somebody could help, it would be greatly appreciated. Thanks!

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(item)

    def list.sort():

You're close, here's couple of hints.

  • you won't need to define another method
  • remember that the list you want to sort is named slots ("self.slots")

Hi, Because you have inherited from Inventory. All methods and variables are available in SortedInventory class. The list you have to sort is called slots from Inventory. So all you need under is to write self.slots.sort() under add Item method

Hi, I've just tried this and it doesn't seem to work

Oli — If the hints here don't work for you, you might want to start a fresh question from within the challenge. Make sure it adds your code and a link as in this one.
