nice, this is a great start

I have just a few comments before we merge the PR:

• let's format the code

pip install black && black .

• this code works great as a script, but we want to eventually publish it as a package in PyPi, for this to be possible we need to modify a few things (which can be done in a separate PRs later)
  • since the _data/ directory is outside the python/ directory, we should have a step that runs before publishing the package, where we essentially move _data/ inside python/ dir.
  • second, consuming the python/_data/ folder as is is not very efficient, thus, we need to modify the previous step, from just copying the _data/ folder over, to first parsing it and converting it into one single data.json file (similar to what we do for other languages)
  • following up on that, we need to modify our python code to just consume that data.json file, meaning that we don't have to pass absulote path in getNodeByPath(path: str) instead only the relative path of the node itself, eg:

    # from this
    getNodeByPath("path-to-_data-folder/umkb/fst/info.json")
    # to this
    getNodeByPath("umkb/fst")

  • finally we get rid of def main() and prepare the python/ folder to be shipped as a package following official docs
