Nvm fixed it. (I was stupid)

I did that but for some reason it didn't work. It also didn't work on other katas. It only works if i put nothing in the function, maybe a problem with codewars?

Do the following: save your code locally (or you will lose it), select the latest Python version (3.8) at the top page of the trainer window, click on reset at the bottom. That will fix the issue.

Traceback (most recent call last):
