利用Process类创建多个子进程对象执行任务，主进程负责调度

import time
from multiprocessing import Process

def run1():
    for i in range(5):
        print("sunck is a good man")
        time.sleep(1)

def run2(name, word):
    for i in range(8):
        print("%s is a %s man"%(name, word))
        time.sleep(1)

if __name__ == "__main__":
    t1 = time.time()

    # 后期主进程主要做的是调度相关的工作，不负责具体业务逻辑
    pro1 = Process(target=run1, args=())
    pro1.start()
    pro2 = Process(target=run2, args=("kaige", "cool"))
    pro2.start()

    pro1.join()
    pro2.join()

    t2 = time.time()
    print("耗时：%2f"%(t2-t1))
