Quick question about Kenneth assigning the class Inventory() = inventory in the repl (2:35)...

Kenneth does this 3 times in the video, and the time stamp 2:35 is the first time he does it. When Kenneth assigns inventory = Inventory() in the repl, is he assigning the class Inventory() to a new variable named inventory so he can call it with ease, or is he doing something else?

This is the code. This file, called inventory, has the class Inventory in it:

inventory.py

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

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

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

    def __contains__(self, item):
        return item in self.slots 

    def __iter__(self):
        yield from self.slots

thanks in advance!

He is creating an instance of Inventory in a variable called inventory.
