How to set constant arguments for pyang in python project

[ahmetoguz1]

I want to make a project that uses pyang.

Basically, I need to create jsonschema from yang model and there is plugin to do that. I want to call pyang with constant arguments in the python project.

I can do that with os.system(pyang -f bla bla) but I do not want to do that like these.

Is there any documentation for use pyang in python?

I would be very happy if someone show me a way. Thanks.
