thought i should add this here so that people will get to this after
someone decides a standard way to do this :P

look for second if condition in the source code of
subprocess.Popen(*args, **kwargs).communicate

    def communicate(self, input=None, timeout=None):
        """Interact with process: Send data to stdin.  Read data from
        stdout and stderr, until end-of-file is reached.  Wait for
        process to terminate.

        The optional "input" argument should be data to be sent to the
        child process (if self.universal_newlines is True, this should
        be a string; if it is False, "input" should be bytes), or
        None, if no data should be sent to the child.

        communicate() returns a tuple (stdout, stderr).  These will be
        bytes or, if self.universal_newlines was True, a string.
        """

        if self._communication_started and input:
            raise ValueError("Cannot send input after starting communication")

        # Optimization: If we are not worried about timeouts, we haven't
        # started communicating, and we have one or zero pipes, using select()
        # or threads is unnecessary.
        if (timeout is None and not self._communication_started and
            [self.stdin, self.stdout, self.stderr].count(None) >= 2):
            stdout = None
            stderr = None
            if self.stdin:
                self._stdin_write(input)
            elif self.stdout:
                stdout = self.stdout.read()
                self.stdout.close()
            elif self.stderr:
                stderr = self.stderr.read()
            [..... extra code snapped]

ps: Python3.5.1
