Does not appear to be a kata issue, the warrior should be level 3 before that fight rather than level 4.

At least that's the case with both the kata reference and top rated solutions.

Can't complete the Kata because of an error in fixed test number 16 ( Python ) the warrior level is 4 and the enemy level is 2, it should be an "Easy fight", but it says it should be "A good fight", wich is wrong because the warrior is 2 levels higher than the enemy so the correct answer should be "Easy fight" and not "A good fight".

UPDATE: I solved it by giving this especific test case what he expected, even if it was wrong, it was the answer the test case wanted.
