分享一个python定时器的例子，有关python time模块的实例。
代码:
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(www.jbxue.com)：
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()
