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.
