python定时器使用示例分享

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

 '''

 if now>=self.__runtime:
 break
 print 'sleeping... %s' % now
 time.sleep(1.0)
 super(SLTimer,self).run()

测试

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()
