ATM , runtime error

Problem Code: HS08TEST

X,Y=map(float,input().split(" "))

if X<Y and X%5==0:
Z=0.5+X
Z=Y-Z
print("{:0.2f}".format(Z))
else:
print("{:0.2f}".format(Y))

This error keeps shooting up every time I run, even get the input as given the problem statement

Traceback (most recent call last):
** File “./prog.py”, line 1, in **
EOFError: EOF when reading a line

Even I tried using Custom input, at the time it shows the output but after submission, it shows up “Runtime error” NZEC

Plz help guys, even I don’t think the logic is wrong for the statement

even after this condition i got the same error!!

Dont use split(" ") use split( ) instead .
