[Answered ]-Python close all threads or processes with subprocess.Popen

You run the Django start script, everything gets initialized and set up and then that newly created Django process goes to background (gets * daemonized*) disconnected from your thread.

So, when you kill that thread, you actually kill nothing because that start-up script has done its job and has probably already exited.

After the start-up script is run, a new Django process is created. Experiment on your machine and find its name. Then you can run something like sudo killall django_process from within your program.
