Question

Halloween Candy +10 XP

You go trick or treating with a friend and all but three of the houses that you visit are giving out candy. One house that you visit is giving out toothbrushes and two houses are giving out dollar bills.

Task
Given the input of the total number of houses that you visited, what is the percentage chance that one random item pulled from your bag is a dollar bill?

Input Format
An integer (>=3) representing the total number of houses that you visited.

Output Format
A percentage value rounded up to the nearest whole number.

Sample Input
4

Sample Output
50

my code:
from math import *
houses = int(input())

if houses>=3:

a=((2/houses)*100)
print(int(round(a)))

Answer 1

In Output it says the result should be rounded *up* to the next integer. You round mathematically.

Answer 2

Lisa i am still having a problem
houses = int(input())

if houses>=3:

a=((2*100)//houses)
print(a+1)

what should i do to print 20 when ipput is 10... and i am having the output 21

Answer 3

I think your approach in the description was already fine. The only thing you woul need to change is the round function.

Instead of round(), you could use ceil() from the math module.
