Super! part 3 has me stumped. Please help!

Please help me understand why my code doesn't pass.

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 Cal,

So when you call super().someMethod, you're already doing everything in the superclass's someMethod method. There's no need to duplicate code already in the superclass's method. In this case, you're adding the item twice! If you delete the line that is already covered by super(), you'll pass.

Cheers :beers:
