Take a look at the subprocess module:

  <URL:
  http://docs.python.org/3/library/subprocess.html#popen-constructor>

It's got the optional close_fds parameter, which is True by default.

IOW, you don't need to do anything if you use subprocess.Popen() to
start your child process. Incidentally, that's the preferred way.
