.. attribute:: Popen.stdin
If the *stdin* argument was :data:`PIPE`, this attribute is a :term:`file
object` that provides input to the child process. Otherwise, it is ``None``.
If the *stdin* argument was :data:`PIPE`, this attribute is a writeable
stream object as returned by :func:`open`. If the *universal_newlines*
argument was ``True``, the stream is a text stream, otherwise it is a byte
stream. If the *stdin* argument was not :data:`PIPE`, this attribute is
``None``.
.. attribute:: Popen.stdout
If the *stdout* argument was :data:`PIPE`, this attribute is a :term:`file
object` that provides output from the child process. Otherwise, it is ``None``.
If the *stdout* argument was :data:`PIPE`, this attribute is a readable
stream object as returned by :func:`open`. Reading from the stream provides
output from the child process. If the *universal_newlines* argument was
``True``, the stream is a text stream, otherwise it is a byte stream. If the
*stdout* argument was not :data:`PIPE`, this attribute is ``None``.
.. attribute:: Popen.stderr
If the *stderr* argument was :data:`PIPE`, this attribute is a :term:`file
object` that provides error output from the child process. Otherwise, it is
``None``.
