EOF when reading a line in competitive website, namely Code Chef

I'm trying to solve a problem using the following code:

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

if X < Y and not X % 5:
    print(Y - X - 0.50)
else:
    print(Y)

This code gives me the desired output when I run using IDLE. However, when I try running this code using an interpreter provided by a competitive programming website, I get the following error:

Traceback (most recent call last):
  File "./prog.py", line 1, in <module>
EOFError: EOF when reading a line

I tried reading the answers of other similar questions, but none of them seemed to work in my case.

I am not sure of the reason but the program is trying to read after the end of the data. You can solve the problem by exception handling

try:
    data = input()
except EOFError:
    break

The competitive programming website is likely running python 2. Python 2 treats input() differently than python 3.

You should rather use raw_input() than input().

From the docs:

raw_input() reads a line from input, converts it to a string (stripping a trailing newline), and returns that.

Your problem can be explained from what was explained here:

In Python 2, raw_input() returns a string, and input() tries to run the input as a Python expression.

Take another look at the codechef page. Notice the checkbox marked 'Custom Input'. With that checked/ticked a textbox will open where you can put your input lines.
