How to run a process in the background

Running a process in background is a typical mode of execution of laborious processes that do not require your presence or intervention, and this course may be concurrent to the execution of other programs. The Python multiprocessing module allows us, through the daemonic option, to run background processes.

How to do it...

To run a background process, simply follow the given code:

import multiprocessing
import time

def foo():
    name = multiprocessing.current_process().name
    print ("Starting %s \n" %name)
    time.sleep(3)
    print ("Exiting %s \n" %name)
    

if __name__ == '__main__':
    background_process = multiprocessing.Process\
                         (name='background_process',\
                          target=foo)
    background_process.daemon = True

    NO_background_process = multiprocessing.Process\
                           (name='NO_background_process',\
                    ...
