Doubts in solving Halloween Candy problem

Question

Hello!
I'm facing this problem. It's Halloween and someone has visited N number of houses. We know 3 of N houses are giving random objects: one is giving toothbrushes and two others are giving money (something like this, cannot remember exactly). So, I'm asked to write a code in which, given an N number as an input where N >= 3, it found the rounded percentage of getting money.
I solved like follows,

houses = int(input())
if houses >= 3:
print(round((2*100)/houses))
else:
print('Please, visit more houses!')

So, it works fine with the two first cases, but it's failing in the rest. And, as I cannot see this rest, I have no clue and cannot figure out where is the mistake. So I've decided to kindly ask for help.
Thanks and regards!

PS: It's written in python

Answer 1

You need to use ceil instead of round function. Try this:

Answer 2

Carefully reread the task description. Two hints:
- What exactly does it say about rounding?
- What does it tell you to do if there are less than three houses?

Answer 3

The number of houses is always >= 3. And you have to round up

Answer 4

Now I see. As a new I did not know the ceil function! Thanks everyone for your help!
