Why not make the Inventory class a subclass of list?

If we want the Inventory class to behave like a list, why not just make Inventory a subclass of list so that it can inherit all of its methods instead of reimplementing them one by one?

Thanks!

That's actually a good implementation idea, but the course is just using the "Inventory" class as an example to show you the process of Emulating Built-ins first.

As it turns out, the very next video is about Subclassing Built-ins.
