Halloween Candy Challenge final 3

Question

I am having issues with the final 3 that it won’t show you the numbers for. My code works perfectly and rounds to the nearest whole number. That’s why I don’t understand why it isn’t working.
#input will be an int (>=3)
houses = int(input())
#get the float chance to pull a dollar
chance = (2 / houses) * 100
decimal = chance
#gets only the numbers after the decimal place
while decimal >= 1:
decimal -=1
#adds one to chance only if 0.5 or greater
if decimal >= 0.5:
chance += 1
#print the chance(ex. 3.9 will print 3, so will 3.49)
print(int(chance))
I’ve seen people using the math import and ceil, but i did the same concept and it didn’t work for the challenge. I’m confused because I tried to make mine as basic as possible. Is there something else the ceil does that I don’t know about?

Answer 1

I just wrote a little test.
Copypaste, run it and see for yourself: The results differ!
from math import ceil
def candy(n):
houses = n
chance = (2 / houses) * 100
print('ceil:', ceil(chance))
decimal = chance
while decimal >= 1:
decimal -=1
if decimal >= 0.5:
chance += 1
print('freestyle:', int(chance), '\n')
for n in range(1, 101):
candy(n)

Answer 2

int basically just cuts the decimals off.
int(3.7) -> 3
ceil(3.7) -> 4

Answer 3

thanks HonFu, i actually started to understand it afterward

Answer 4

somehow i cant solve this challenge, after see your conversation about ceil i think i understand why any of my solution isnt working.
it looks like i misunderstood the question and only took "nearest whole number" as the problem i need to solve instead of "round up the number"

Answer 5

thanks HonFu, but doesnt my while and if loop do the same? for instance when the number 3 is put mine still shows 67%...
its only rhe bottom three that dont work

Answer 6

I just ran it again and made a screenshot.
Look closely at the numbers: Some do differ!

Answer 7

yeah, so if its 3.4 you need 3 and if its 3.6 you need 4

Answer 8

A lot of people missed that, in several tasks.
