To my knowledge there isn’t a python client for the rest API, so I’ve started building one here: https://github.com/isears/openmrsapi
It’s something I’m personally using to more efficiently manage an OpenMRS installation. It’s fairly primitive right now but I’m posting here in case any fellow pythonistas are interested in using/contributing.
Actually, REST endpoints don’t need any language requirements while getting access from those(language independent). We can call a Java REST endpoint from Python or NodeJs and even we can call it from anywhere.
OpenMRS has a strong REST implementation based based on Java. You can get it from here,
Anyway,
OpenMRS may have a python REST based backend in the future 
. Hope your idea will be paid off.
Thanks for sharing @isears. This looks like a better approach compared to the hacky omrs-rest-client I created a while ago.
