For running commands in Python without going through a shell, you might
find this function I wrote for arch-pqm useful:

def popen_noshell(cmd, *args):
    (stdin, stdout) = os.pipe()
    pid = os.fork()
    if pid == 0:
        os.close(stdin)
        os.dup2(stdout, 1)
        os.dup2(stdout, 2)
        os.execvp(cmd, [cmd] + list(args))
        os.exit(1)
    os.close(stdout)
    output = os.fdopen(stdin).readlines()
    (pid, status) = os.waitpid(pid, 0)
    msg = ''
    if not (status is None or (os.WIFEXITED(status) and os.WEXITSTATUS(status) 
== 0)):
        if os.WIFEXITED(status):
            msg = "%s exited with error code %d" % (cmd, 
os.WEXITSTATUS(status),)
        elif os.WIFSTOPPED(status):
            msg = "%s stopped unexpectedly with signal %d" % (cmd, 
os.WSTOPSIG(status),)
        elif os.WIFSIGNALED(status):
            msg = "%s died with signal %d" % (cmd, os.WTERMSIG(status),)
    return (status, msg, output)
