small note - it's more Pythonic to check if a list is empty by doing if not list rather than if len(list) == 0

Nice usage of self.swap_items() ✨

small note - you can create a dictionary and specify its values in the same line. So, line 64 could be best_dict_category = {consider_category: 0.0} and you wouldn't need line 65.

small note - variable names should describe the data they are holding. category_from_inv is holding items, not their categories. If you were working in a team of developers, this could cause confusion for other people. Something you might find helpful - before I consider any code I write finished, I like to think about how easy it would be for someone else to pick up my code and understand it.

Something to consider - Python doesn't create a local scope for loops which is why you can return best_category outside of the loop. However, most other languages don't allow access to variables created inside of loops. Going forward, it could be good to treat loops as having a local scope to build that habit.

- Careful with how you are combining conditional statements with
and. The!= 0check isn't being applied tolen(self.inventory). In order to apply it to both lists, this should be written asif len(self.inventory) != 0 and len(other.inventory) != 0:. Python knowslen(self.inventory)evaluates to a truthy value, which is why your version still works. - This line of code can be simplified to be
if self.inventory and other.inventory:because Python knows to evaluate an empty list as False. This way is also considered more Pythonic. - Consider if this conditional statement is even necessary. Input validation is great but sometimes the rest of the code is set up in a way that it isn't necessary to validate the input. Does the
get_best_by_category()method know how to handle empty lists? If so, is it necessary to check that the list isn't empty here?

Strings are immutable objects so it's safe to set an empty string as a default value in your parameters :)

Love that you're using the repr() function!

In the future, don't worry about commenting out @pytest.mark.integration. This decorator just specifies that these tests are integration tests so they should run after all the unit tests have been executed. :)
