Used functions not counted for progress - python coding challenges

Used functions not counted for progress

Hey,

I am trying to level up my profile progress stage and therefore I am trying to use the proposed functions (where you should sue 5/6 at least). Specifically, I used isinstance(), functools(), and itertools() in some succesfulyl solved missions, but it seems they do not count. Am I missing something?
