what division bro

Don't feel bad, everyone has to learn at some point, check the sample tests about how the input/output is formatted. Don't use a global var, use your function argument.

now I read it carefully and yeah its wrong, the problem is that I dont speak english natively and I need to understand the instructions in my own language and also the coding concepts and I cant handle that much as a beginner, sorry

But the thing works on my pycharm but here it tells me that n has no lenght, and should I code the numbers as an int input? maybe that was it

Because your code is wrong and it doesn't take a number as input, also, it should return the result.
