Question

I\'m trying to run two functions simultaneously in Python. I have tried the below code which uses multiprocessing but when I execute the code, the second functi

This is a very good example by @Shashank. I just want to say that I had to add join at the end, or else the two processes were not running simultaneously:

from multiprocessing import Process
import sys

rocket = 0

def func1():
    global rocket
    print 'start func1'
    while rocket < sys.maxint:
        rocket += 1
    print 'end func1'

def func2():
    global rocket
    print 'start func2'
    while rocket < sys.maxint:
        rocket += 1
    print 'end func2'

if __name__=='__main__':
    p1 = Process(target = func1)
    p1.start()
    p2 = Process(target = func2)
    p2.start()
    # This is where I had to add the join() function.
    p1.join()
    p2.join()
