python定时器使用示例分享

代码如下:

class sltimer(multiprocessing.process): #from datetime import datetime #import time

def __init__(self, target=none, args=(), kwargs={},date=none,time=none): ”’\ @param date 1900-01-01 @param time 00:00:00 ”’ super(sltimer,self).__init__(target=target,args=args,kwargs=kwargs) _date = ” if date is none: _date = datetime.now().__str__()[:10] else : _date = date

_time = ” if time is none: _time = datetime.now().__str__()[11:19] else: _time = time

self.__runtime = ‘%s %s’ % (_date,_time)

def run(self): timelen = len(‘1900-00-00 00:00:00’)

while true: now = datetime.now().__str__()[:timelen] if now>=self.__runtime: break print ‘sleeping… %s’ % now time.sleep(1.0)

super(sltimer,self).run()

测试

代码如下:

def show1(): from datetime import datetime print ‘hello,current time:%s’ % datetime.now().__str__()

def t23(): from stock.task import sltimer

timer = sltimer(show1, time=’16:31:50′) timer.start()
