Fix Python Example main.py

FIXME: Get Node ID

Add Pre-Commit and Ruff in Github Actions

I doesn´t know gh actions enough. Maybe yaml files are not correct in this repo. Sry but would show you the python format actions

thanks, the main.py file was fixed in #201, I don't think we want to add precommit hooks to this repo, but if want to update the PR to just use ruff in ci that would be good to have
