How can I start and stop a separate python script from a flask web interface?

Question

I have a python script that runs continuously on a server using a ‘while true’ loop. This script gets started and stopped arbitrarily and can’t be scheduled.

I would like to control it from a flask app - a single page application that just has a button to toggle the script to either start or stop depending on its current status.

I have the flask app, and I have the script, but I can’t figure out how to run the script separately - outside of the flask app.

Define two routes, first will launch process and save it in some global context, second will terminate this process. — Olvin Roght, Jun 13 '22 at 15:19

In your script, on each iteration, check some flag (database, file) to decide whether or not to execute.

In you app, act upon this flag.
