I don't know where I am wrong here

For the ATM PROBLEM, this was my code. It worked in other IDEs but I am getting a NZEC error here. I’m so confused.

Please help!!

You need to just take input of two integers. Use a map and take the inputs in floats.
Here is your AC code

x,y = map(float,input().split())
if x%5==0 and x+0.5<=y:
    s=y-x-0.5
    print(s)
else:
    print(y)
