also note - there was a mention somewhere of seeking yaml-style output.

there is a yaml module which can help with the emitting part without 
having to worry about the formatting yourself (actually, to be honest, 
there are actually *many* yaml modules.  pyyaml is, I believe, the most 
popular - at least it's the one used by some very popular Python 
packages like django, docker compose, the kubernetes Python client, etc)
