Why do we not need to use self when using super() to override add_item?

Why do we not need to use self when using super() to override add_item?

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)

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)

You do use "self" in the definition of "add_item", as the first parameter. This is typical for any method definition.

You don't use it when you call a method, that's also typical. The system adds that for you.
