Help I am stuck!! How do I override add_item method?????

I am stuck a little so please someone explain what do I need to do in this challange??? And please explain super() function a little. I do understand that it takes piece of parent class and make a copy of that which you can use, but how do you do that is still mystery for me :(

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):

Yes! You need to call your Inventory class from SortedInventory class by creating new method in SortedInventory class and in that method using super() function. And then for 3th task you need sort list with list.sort(). My whole code looks like this: 

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

    def add_item(self, item):
        self.slots.append(item)
class SortedInventory(Inventory):
    def add_item(self):
        super().add_item(item)
        list.sort(self.slots)

Hope that will help you !

I copied the code over to my challenge, but it doesn't work. Did that work to you?

I figured it out. You have to do 

def add_item(self, item):

and not 

def add_item(self):

I cannot move on from this task. I have tried everything I can think of, and even copied and pasted the code recommended in previous answer, but it still won't get accepted as correct. As usual (don't understand why!), we get no feedback as to why the code is wrong, not even which line is causing the problem, so at this point I am just guessing any combination of words. Any help appreciated.

Task 2/3

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

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