Sorting inventories (3/3)

I really don't get what is wrong with my code. It seems right to me, but not working :(

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) 
        self.slots.sort()

Hi there, Simla Sophia Yildirim ! From what I can tell, there's nothing wrong with your code at all. In fact, when I copy/paste it into the challenge, it passes all steps. This leads me to believe that there might be a caching problem either client-side or server-side. I might suggest copying this code, and completely restarting the challenge then pasting it in. If that doesn't work, you might consider logging out of Treehouse, shutting down your browser, logging in again and then pasting in the code.

But this code should work! :sparkles:

Oh thank you so much Jennifer Nordell :)

Part 2 asks you to add items into the "slots" list. Which looks like this:


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)
        self.slots.append(item)

In part 3, you actually have to replace the "self.slots.append(item)" with "self.slots.sort()". Rather than adding "self.slots.sort()" to the already existing code from the previous part of the challenge. It took me a while to figure this out. Hope that helps :)
