If omitted, ``None`` or negative, wait until an event occurs. Return a list of all events that occurred before ``timeout``, where each event is a pair ``(fd, event)``. ``fd`` is the integral file descriptor, and ``event`` a string indicating the event type. If ``'r'``, there is data to read from ``fd``. If ``'w'``, ``fd`` is writable without blocking now. If ``'h'``, the file descriptor was hung up (i.e. the remote side of a pipe was closed). )�list� _parse_eventsr r r )r �timeouts r r z Poll.pollJ s, � �" �D�&�&�'7����8K�8K�W�'U�V�W�Wr c # �� K � |D ]� \ }}| j |t j � rt dt |� � �� �| j |t j � rt dt |� � �� �| j |t j � r|df�� | j |t j � r|df�� | j |t j � s��|df�� �� y�w)z�Parse ``events``. ``events`` is a list of events as returned by :meth:`select.poll.poll()`.
