When you hating a short ways:

I don't really get this. Do i need to create a random list of values or i need to input them? Please, give me a little hint of way that i can do that

Wow, can you explain it to me, cause i'm not really understand Python much yet?

Вот так вот смотрю на чужие решения и понимаю: насколько же я долбанулся. У всех всё компактно... Объясни, пожалуйста, свою программу

Problem solved! Thank you!

Thank you , but i still have a problem, now it is:
Traceback (most recent call last):
File "main.py", line 1, in
from solution import *
File "/home/codewarrior/solution.py", line 32, in
descending_order(a)
NameError: name 'a' is not defined

I've typed return in the end of function
