The minimum port in the range of ports to try (inclusive).
max_port : int, optional
The maximum port in the range of ports to try (exclusive).
max_tries : int, optional
The maximum number of bind attempts to make.

The zmq.SNDMORE flag is added to all msg parts before the last.
Parameters
----------
msg_parts : iterable
A sequence of objects to send as a multipart message. Each element
can be any sendable object (Frame, bytes, buffer-providers)
flags : int, optional
SNDMORE is handled automatically for frames before the last.
copy : bool, optional
Should the frame(s) be sent in a copying or non-copying manner.
track : bool, optional
Should the frame(s) be tracked for notification that ZMQ has
finished with it (ignored if copy=True).
Returns
-------
None : if copy or not track
MessageTracker : if track and not copy
a MessageTracker object, whose `pending` property will
be True until the last send is completed.

W| S( s� receive a multipart message as a list of bytes or Frame objects
Parameters
----------
flags : int, optional
Any supported flag: NOBLOCK. If NOBLOCK is set, this method
will raise a ZMQError with EAGAIN if a message is not ready.
If NOBLOCK is not set, then this method will block until a
message arrives.
copy : bool, optional
Should the message frame(s) be received in a copying or non-copying manner?
If False a Frame object is returned for each part, if True a copy of
the bytes is made for each frame.
track : bool, optional
Should the message frame(s) be tracked for notification that ZMQ has
finished with it? (ignored if copy=True)
Returns
-------
msg_parts : list
A list of frames in the multipart message; either Frames or bytes,
depending on `copy`.
