Start a process and redirect its stdout and stderr to /dev/null.

start_process.py

try:
    from subprocess import DEVNULL  # Python 3.
except ImportError:
    DEVNULL = open(os.devnull, 'wb')


def start_subprocess(cmd):
    """Run cmd (a list of strings) and return a Popen instance."""
    return subprocess.Popen(cmd, stdout=DEVNULL, stderr=DEVNULL)

Thanks, just what I needed.

Thank you!!!
