python multiprocessing模块多进程

实现方式

1.引入模块
2.实例Process()
3.start()
4.join()

Demo

import os
from multiprocessing import Process
def run(name):
    print 'Child process %s(%s) Running...' % (name,os.getpid())
if __name__ == '__main__':
    print 'parent process %s.' % os.getpid()
    for i in range(10):
        p = Process(target=run, args=(str(i),))
        print 'Process will start...'
        p.start()
    p.join()
    print 'Process end.'
