I don't get what i'm supposed to do

I used the list.sort() to sort my list but it does not accept my answer, did I do something wrong ?

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()

Hi there,

You don't need your line self.slots.append(item) as that's what the call to `super does. If you remove that line, your code looks OK - at the moment, you're adding item to the list twice.
