I'm interested in using a python library in elisp for a quick hacki
project and found this
https://github.com/pinard/Pymacs
Is there any modern versions or will this still work?
If not would wrapping stuff in calls to elpy be the best option or
should I just write the python commands I want to use as individual
scripts then call them through the shell command functions?
In case it's relevant the library is
https://pypi.org/project/FlightRadarAPI/

You can [call python process directly](https://www.gnu.org/software/em
acs/manual/html_node/elisp/Synchronous-Processes.html), you don't need
to go through the shell.

    (defun run-python-script (script)
      "Exec python script and return the result string."
      (with-temp-buffer
        (call-process "python3" nil t nil script)
        (buffer-string)))

    (message "Hello from Python: %s"
      (run-python-script "/home/arthur/repos/test.py"))

My example is pretty hard coded, you would probably  abstract search
paths to your script etc, but just as an example.

calling python scripts is ok, but it looks like the REST API is so
simple you can call it from Elisp directly
