Hi Lynn! Your project has been scored as green.
There are several methods in your Vendor class where a try-except block could be implemented to improve time complexity. Checking to see if an item is in a list before doing something with it, is an O(n) operation. So, see if it's possible to replace those if statements with a try-except block instead. :)
Nice job! You can find my comments in your code. Let me know if you have any questions! 😊

Be sure to read the instructions and test names carefully! the Vendor remove method is supposed to return False if the item is not found.

Pay attention to what each line of your code is doing and if it serves a purpose. What is this loop doing? condition_description() is a method, but this line does not call it since it's missing the ending parentheses. Even if it were calling the method, the output is not being saved anywhere to be used again.
I'd recommend doing a pass over your code after it's working to do some refactoring and clean up. :)

Nice! Love that you're paying attention to code coverage! ✨

| assert item_e in jesse.inventory |
| # - That tai and jesse's inventories are the correct length | ||
| # - That all the correct items are in tai and jesse's inventories | ||

Nice job writing your own tests for newest items! 🥳

Great job with wave 5 and using inheritance! Nice work hardcoding the category too 🥳

This approach works, but consider how a try-except block could improve your time complexity. 🤔 💭 😌
| if len(self.get_by_category(category)) == 0: | ||
| return None | ||
| else: | ||
| return max(self.get_by_category(category), key=lambda item: item.condition) |

Oooo! Great usage of the max() function with a lambda function!! 🤩

Since a list with 1 or more values is truthy, the Pythonic way to write this if statement would be:
if self.inventory:

| else: | ||
| return False | ||

Great job with the optional enhancements! 🎉
