I am also lost. What is a decimal representation?

While I agree it can be improved as you said, I consider something as a kata issue if the user can't fix it changing his/her code. In this case, the problem comes from the user returning a different datatype from the expected one, and it can be fixed by the user, returning the expected one.

I would still consider crashing tests a kata issue. If tests want to use the returned value in a non-trivial way, it should be sanitised and not cause a crash.

Given s and x the task is to return as an integer ...

Well, you're returning a list instead of a number, that's your code's problem, not a kata issue.

I get a TypeError no matter what I do, whether I am testing or attempting the solution.

The problem seems to be the "testing" function defined. I get:

Traceback (most recent call last):
  File "tests.py", line 18, in <module>
    testing(gps(s, x), u)
  File "tests.py", line 6, in testing
    r = fabs(actual - expected)
TypeError: unsupported operand type(s) for -: 'list' and 'int'

The list type just changes to 'None' if I just return nothing. Can anybody help?

Reviewed, Forked & Approved. (Honor points goes to you)

Beutiful.

yes and no

It is time to learn boolean :)

🔪

Today i learned: You can do this

im asking why people vote it as cleaver ?

I dont C/P. I am printed, dude...

This is what you have to figure out by yourself. The description gives all the elements to find the result. Minimum height posible just means what it says: if you find some combination but there exists another possibility that satisfies all the other requirements with 1st being lower, then your solution is incorrect. It's not as obvious as one could think at first sight, but I think any hint would definitively spoil the solution. If you cannot find it out, a good option can be to move on to other katas. Someday maybe the answer will pop into your mind with clarity.
