You need to add a Scripting Engine that can run Phyton. There is support for Jyton:

Camunda Platform supports scripting with JSR-223 compatible script engine implementations. Currently we test the integration for Groovy, JavaScript, JRuby and Jython. To use a scripting engine it is necessary to add the corresponding jar to the classpath.

See the documentation: https://docs.camunda.org/manual/7.17/user-guide/process-engine/scripting/

I haven't done that - but here is a discussion on how to use Camunda with Python: https://forum.camunda.io/t/python-integration-with-camunda/8846/2
