Can't understand what I have to do here.

Okey how I understood was that I could access the data from the parent with the super() method and a dot, so if I need a method it would be like. super.method(params).. I guess it's like a prototype for methods in JavaScript. But not sure. please help??

The instruction:

Great! Now override the add_item method. Use super() in it to make sure the item still gets added to the list.

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

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

class SortedInventory(Inventory):
     def __init__(self):
        super().item

In your answer to Task 1, you do not have to override the __init__ method. If it is not defined in SortedInventory, the __init__ method in Inventory will automatically be found and executed. For Task 1, the body of SortedInventory could simply be pass

For Task 2, to override a parents method, create a local method with the same name and signature: def add_item(self, item): Then use super() to call the parents version of the method using super().add_item(item)

I'll leave you to the work out Task 3. Hint: you only need to add one additional line to the add_item method in SortedInventory to modify self.slots to be sorted.

Post back if you need more help. Good luck!!
