Code works perfectly on my end but the quiz says otherwise.

On workspaces it works and on my command prompt it works. I am able to add items using the add_stuff method. I'll give you an example of a test I just did.

warehouse = SortedInventory()

warehouse.add_stuff("zebra")

warehouse.add_stuff("apple")

warehouse.slots

OUTPUT ["apple", "zebra"]

The code ended up sorting the list after apple was added. If it wasn't sorted then zebra would have been at index [0] and apple would have been in index [1].

At this point I don't know what to do and I don't want to look up an answer.

Thanks!

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

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

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

Hi Jacinto,

It's not working, because you are not overriding the correct method.

I'm not sure why the code checker passed the code for Task #2 as you are using a different named method that is meant to override a parent method. Weird? (Tagging Kenneth Love to have a look :eyes:)

In your SortedInventory Class, you have def add_stuff when it should be def add_item. Once you make that correction, all 3 tasks pass.

Keep Coding! :dizzy:

Thanks for pinging me on this. I've updated the CC to handle this kind of case.

Thank you! That helped a lot! I thought the quiz wanted me to override the parent class method with a different method. That's the reason why I decided to change the name. When it passed on Task #2 I thought I was on the right track. Honestly, does the name of the function even matter if it outputs the same result? In any case, I was stumped on this for quite a while. Thanks again for the quick response and help!
