Overriding methods using super()

The whole concept of using the super() to use a method from a parent class is entirely confusing and now I tried overriding the add_item method but the code won't work. What really is the purpose of super() and how is it used? I have repeated the tutorial like the 6th time now but I'm failing to get the sense around it all and also how to use it. Please help. A detailed explanation can be handy too because I literally have 0 idea of what I am doing. Thanks in advance.

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

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

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

Using "super" allows you to call a method in the parent class that has the same name as one in your derived class.

The main issue here is that this code is overriding "__init__" , but the instructions ask you to create an override for "add_item" instead. You won't need to override "__init__" in this challenge.
