用python得Tornado框架做web Demo，数据的预加载终于搞定了，不用每一次post都要load一次数据了，加快了执行速度。

def load_data():          return *class Application(tornado.web.Application):    def __init__(self):        handles = [            (r'/', IndexHandler),            (r'/result', ResultPageHandler),        ]        settings = dict(            template_path=os.path.join(os.path.dirname(__file__), 'templates'),            static_path=os.path.join(os.path.dirname(__file__),'static'),            debug=True,        )        tornado.web.Application.__init__(self,handles,**settings)        s=clock()        self.feadata = load_data()        e=clock()        print (e-s)        print "loading data done!"def main():    tornado.options.parse_command_line()    http_server = tornado.httpserver.HTTPServer(Application())    http_server.listen(options.port)    tornado.ioloop.IOLoop.instance().start()
