PyMQI is a production-ready, open-source Python extension for IBM MQ (formerly known as WebSphere MQ and MQSeries).

For 20+ years, the library has been used by thousands of companies around the world with their queue managers running on Linux, Windows, UNIX and z/OS.

To put a message on a queue:

import pymqi

queue_manager = pymqi.connect('QM.1', 'SVRCONN.CHANNEL.1', '192.168.1.121(1434)')

q = pymqi.Queue(queue_manager, 'TESTQ.1')
q.put('Hello from Python!')

To read the message back from the queue:

import pymqi

queue_manager = pymqi.connect('QM.1', 'SVRCONN.CHANNEL.1', '192.168.1.121(1434)')

q = pymqi.Queue(queue_manager, 'TESTQ.1')
msg = q.get()
print('Here is the message:', msg)

PyMQI is a low-level library that requires one to know IBM MQ APIs well.

It serves, however, as the basis for IBM MQ support in Zato, which is an enterprise API platform and backend application server in Python that lets one connect to many technologies with little or no programming.

This includes IBM MQ queue managers as well as the ability to seamlessly integrate with Java JMS systems.
