What is wrong with my code please?

Sorted inventories should be just that: sorted. Right now, we just add an item onto the slots list whenever our add_item method is called. Use the list.sort() method to make sure the slots list gets sorted after an item is added. Only do this in the SortedInventory class.

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)
        self.slots.sort()

All you need to do is remove the 

self.slots.append(item)

from your SortedInventory class

Thank you. Could you please explain why?

I think it's because the self.slots.append(item) is inside your add_item function which you supered already.
