An easier way to execute programs is to use the functions defined in 
System.Process, e.g.:

import System.Process

main :: IO ()
main = callProcess "/usr/bin/python" ["/my super/script.py"]

Note that 'callProcess' takes a list of strings, each element being one 
argument. The elements may contain spaces.
