My code appears not to work! Why?

Question

Hi, coders,

I need your help. There is this challenge in the code coach:

https://www.sololearn.com/coach/4?ref=app

This is my code to solve it:

houses=int(input())
while houses<3:
houses=int(input())
ptg=2/houses*100
print(round(ptg))

In the code coach, the first two test cases are OK (my output and the expected output match), but the rest of them say that my output obviously does not match the expected output.

Where am I making a mistake?

Thank you!

Answer 1

The task is to round up the result!

Thank you so much! My bad! I did not read the problem carefully enough. It fits now. :-)
