Getting error: "'Inventory' object has no attribute 'slots'"

I copied and pasted the file into Pycharm and I'm getting that Inventory has not attribute slots. Can anyone help or explain why this is happening? Thanks in advance:

class Inventory:

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

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

    def __len__(self):
        return len(self.slots)

[MOD: added ```python formatting]

What exactly are you doing when you get the error?

You have to first instantiate an instance of inventory and then you will have access to the slots attribute.

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

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

    def __len__(self):
        return len(self.slots)

my_inventory = Inventory() # instantiates an inventory class and assigns it to my_inventory variable
my_inventory.slots  # []

Your doing it almost completely correct but I believe you have to define inventory and inventory.slots then i believe your solution would work.
