Codecoach - Halloween candy please help

Question

I am learning python and using code coach - one specific problem I couldnt get right its called halloween candy. I dont know how to attach it to this post. But the code I wrote to solve it is:

print (round (2/houses) + int (2/houses * 100))

I get the first two scenarios correct but the hidden test scenarios are wrong. I dont know what is the problem.

And is there a way to see the hidden test scenarios in code coach? I am mostly using the sololearn phone app to code and study.

Answer 1

I see that you made a hopeful attempt to always round up, but it doesn't work. Solution: There is a function in the math library that always rounds up. Import the math library and use math.ceil().

Answer 2

It sounds like you are endeavoring to understand how to write your own ceil function. Here is how I would write it:

def ceil(a):
return int(a)+(a>int(a))

Answer 3

import math

dollar = math.ceil(2/(int(input()))*100)

print(dollar)

Answer 4

I should still be able to solve it without importing math.ceil

I believe one of the scenarios is wrong. Here is my logic.

I get 4 out of 5 scenarios correct if I code (rounding down all decimals):
Print (int (round(2/houses) *100))

And I get one out of scenario correct if I round up all the decimals using the following code:
Print (int (round(2/houses) * 100 +1))

So the code should be able to round up or down . As the following:

houses = int(input())
x = round (2/houses)

if int (x) == 0:
print (int (2/houses * 100))
elif int(x) > 0:
print (int (2/houses *100) + 1)
Yet still it only solves 4 scenarios out of 5.

If you could share the code to solve, and if possible without the math.ceil

Answer 5

I solved it using math.ceil, with the following code:

houses = int(input())
x = (2/houses)

import math
print (math.ceil(x * 100))

Still th previous solution should have worked.

Please be patiant with me, I am trying to understand the logic behind the codes.

Thank you very much gentlemen
