TypeError: add() missing 1 required positional argument: 'arr'

I am having this problem. I think it's not related to my function or is it?

Hello, firstly thank you for the exercise but it was a little bit tricky for me to understand at the beginning. Because I first thought that you want from us to compare the amount of letters in the word. Then I figured out that I should compare the places of the words not the amount of letters in the word. If you add some more explanations about this it might be better for the other users.
