If you want to write a program, you need to have some code that
actually does something (rather than just containing definitions of
functions). Here's a trivial example of a file using your sum
function:

#!/usr/bin/env python

def sum(x, y):
        return x+y

print 'Enter two numbers:'
x = int(raw_input())
y = int(raw_input())

print 'The sum is equal to %s + %s = %s' % (x, y, sum(x,y))
