in python you will want to import json for handling json.

Here's how to use the json library: https://docs.python.org/2/library/json.html

I would not use cherrypy here though. cherrypy is deprecated in Splunk.

GIve this a read: https://conf.splunk.com/files/2016/slides/extending-splunks-rest-api-for-fun-and-profit.pdf

and refer to the github link at the end of the presentation for sample code.
