I am looking for an MQ Client to use with Python \ Jython.
Looking for a stand-alone program so that I dont have to install anything in the machine I am running as it may have to be run on multiple machines. So I guess Websphere is ruled out. Want something which is stand alone, may be a jar that can be imported through Jython but if something could work using Python compiler and additional library that would be great.
As well as the download of the redistributable client that JoshMc mentions, you might be interested in the fact that the MQ jars are also available through Maven https://developer.ibm.com/messaging/2018/01/09/developing-mq-java-applications-maven/
There are also open source ways to talk to MQ with Python. For a simple pub/sub API there is the MQ Light API that talks AMQP to MQ (client can be found here https://github.com/mqlight/python-mqlight).
There's also the PyMQI project (https://pythonhosted.org/pymqi/), this requires an MQ client on the system, so you'd use the same redistributable MQ client package to obtain that.
