3/3 list sort task.

I feel like the sort should go inside the dunder method. I'm not getting any errors towards syntax but I could be wrong in many senses of the task

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

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

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

The instructions say specifically to put the sort "In the SortedInventory's add_item method".

The sorting is the main purpose of this new class. No changes should be made to the original "Inventory" class.

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 :)
