Python: Show the individual process IDs involved
Python Basic - 1: Exercise-118 with Solution
In multiprocessing, processes are spawned by creating a Process object.
Write a Python program to show the individual process IDs (parent process, process id etc.) involved.
from multiprocessing import Process import os def info(title): print(title) print('module name:', __name__) print('parent process:', os.getppid()) print('process id:', os.getpid()) def f(name): info('function f') print('hello', name) if __name__ == '__main__': info('Main line') p = Process(target=f, args=('bob',)) p.start() p.join()
Main line module name: __main__ parent process: 23967 process id: 27986 function f module name: __main__ parent process: 27986 process id: 27987 hello bob
