OOP Code Challenge Super! difficulties

I got to the third task

"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. In the SortedInventory's add_item method, use the list.sort() method to make sure the slots list gets sorted after an item is added."

I can't seem to figure out where exactly to put the list.sort() method, nor how to be sure it is sorted after an item is added. I feel like I have missed something from previous videos but I am not sure what

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 sort_items(slots):
            list.sort()

You don't need a separate sort_items method; you just add list.sort() directly below the super().add_item(item) in the add_item method; make sure to replace list with the appropriate variable. Hint: it begins with self.
