Well, he can do the following stuff:
-) wrap it in a shell script that changes to current directory to the
expected one.
-) do that inside the python script.
-) make the file path absolute somehow:
   *) code it as a constant int the script.
   *) make it an argument (see sys.argv or module optparse)
   *) make it an argument via the environment (os.environ, not getenv)
