I am creating a little dashboard for a user that will allow him to run specific jobs. I am using Django so I want him to be able to click a link to start the job and then return the page back to him with a message that the job is running. The results of the job will be emailed to him later.
I believe I am supposed to use subprocess.Popen but I'm not sure of that. So in pseudocode, here is what I want to do:
if job == 1: run script in background: /path/to/script.py return 'Job is running'

cmd /k is the typical way to open any console application (not only Python) with a console window that will remain after the application closes. The easiest way I can think to do that, is to press Win+R, type cmd /k and then drag&drop the script you want to the Run dialog. Fantastic answer. You should have got this.
It happens nothing. Once the script is loaded in memory and running it will keep like this. An "auto-reloading" feature can be implemented anyway in your code, like Flask and other frameworks does.
Challenge: Run a piece of Python code forever—until it is forcefully interrupted by the user. Solution: use a while loop with a Boolean expression that always evaluates to True . Examples: have a look at the following variants of an infinite while loop.
p = subprocess.Popen([sys.executable, '/path/to/script.py'], stdout=subprocess.PIPE, stderr=subprocess.STDOUT) That will start the subprocess in background. Your script will keep running normally.
