It is related to it, you have to write your code in order to avoid that error, not a kata issue.

Looks like you are missing an aterisk in function parameter.

Traceback (most recent call last):
File "/workspace/default/.venv/lib/python3.11/site-packages/codewars_test/test_framework.py", line 112, in wrapper
func()
File "/workspace/default/tests.py", line 9, in basic_tests
test.assert_equals(add(), 0, 'No arguments should return 0')
^^^^^
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.
