I totally agree that the task is above the 8 kyu level. However, I have to say that it can be solved via coding (and very basic coding) rather than digging into docs.

Ok, I see what you mean now, I was more focused in the difference in these two:

import codewars_test as test
from solution import remove_exclamation_marks

@test.describe("Fixed Tests")
...
test.describe("Fixed Tests")

An empty string is as valid as any other string.

In your first post you said those should be the tests, what's wrong with them?

Click Reset. I don't see that.
