Your example is too heavily contrived for me to give a much more
specific/useful answer than "use the `subprocess` module":
http://docs.python.org/2/library/subprocess.html#using-the-subprocess-module

Of course, if all you want to do is manipulate environment variables,
then there's `os.environ`:
http://docs.python.org/2/library/os.html#os.environ

Good luck, my pseudonymous contrarian compadre.
