python 多进程创建 使用multiprocessing

import multiprocessing
import time

def clock(interval):
    while True:
        print ("the time is %s"% time.time())
        time.sleep(interval)

if __name__=="__main__":
    p = multiprocessing.Process(target=clock,args=(15,))
    p.start()  #启动进程

"""
定义进程的另一种方法，继承Process类，并实现run方法
"""
class ClockProcessing(multiprocessing.Process):
    def __init__(self, intverval):
        multiprocessing.Process.__init__(self)
        self.intverval = intverval
    def run(self):
        while True:
            print ("the time is %s"% time.time())
            time.sleep(self.interval)

 

if __name__=="__main__":
    p = ClockProcessing(15)
    p.start()  #启动进程
