本文实例讲述了python基于multiprocessing的多进程创建方法。分享给大家供大家参考。具体如下:

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:

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

希望本文所述对大家的Python程序设计有所帮助。
