great use of a dict here. And if/else block would take O(n) worse case to fall through to the last condition!
Plus, nice formatting of the contents of the dict here

Okay, this is clean code that only loops through the whole thing once. In a more complex project, you can probably see how we could use things like filter to pull specific sets out of the inventory. Well done, though!

Nice use of OOP-based similarity enhancement!

Ah, and there's filter. Good use of it here!
