python connect to MQServer

we need install mqsdk and mqclient before install pymqi
sudo apt install ./ibmmq-sdk_9.1.5.0_amd64.deb
sudo apt install ./ibmmq-client_9.1.5.0_amd64.deb
pip install pymqi
export LD_LIBRARY_PATH=/opt/mqm/lib64:$LD_LIBRARY_PATH

create a user ID on the server that is not in the mqm group.

(base) ubuntu@ubunu2004:~$ python test_mq.py
then you can verify it with amqsget:

mqm@ubunu2004:/opt/mqm/samp/bin$ ./amqsget QUEUE1 QUEUE.MANAGER.1
Sample AMQSGET0 start
message <Hello from Python!>
no more messages
Sample AMQSGET0 end
