336       Popen(['/bin/sh', '-c', args[0], args[1], ...])

458 Popen Objects
461 Instances of the :class:`Popen` class have the following methods:
464 .. method:: Popen.poll()
467    :attr:`~Popen.returncode` attribute.
470 .. method:: Popen.wait()
473    :attr:`~Popen.returncode` attribute.
483 .. method:: Popen.communicate(input=None)
493    the Popen object with ``stdin=PIPE``.  Similarly, to get anything other than
503 .. method:: Popen.send_signal(signal)
516 .. method:: Popen.terminate()
525 .. method:: Popen.kill()
537    Use :meth:`~Popen.communicate` rather than :attr:`.stdin.write <Popen.stdin>`,
538    :attr:`.stdout.read <Popen.stdout>` or :attr:`.stderr.read <Popen.stderr>` to avoid
543 .. attribute:: Popen.stdin
