python基于multiprocessing的多进程创建方法

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

import multiprocessing
import time
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
