from tornado import web, ioloop
    import datetime
    period = 5 * 1000   # every 5 s
    class MainHandler(web.RequestHandler):
        def get(self):
            self.write('Hello Tornado')
    def like_cron():
        print datetime.datetime.now()
    def xiaorui():
        print 'xiaorui 2s'
    def lee():
        print '  wansuilee 3s'
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
    if __name__ == '__main__':
        application = web.Application([
            (r'/', MainHandler),
            ])
        application.listen(80)
        ioloop.PeriodicCallback(like_cron, period).start()  # start scheduler
        ioloop.PeriodicCallback(xiaorui, 1000).start()  # start scheduler
        ioloop.PeriodicCallback(lee, 3000).start()  # start scheduler
        ioloop.IOLoop.instance().start()
