 “Hello, world” 示例：

import tornado.ioloopimport tornado.webclass MainHandler(tornado.web.RequestHandler):    def get(self):        self.write("Hello, world")application = tornado.web.Application([    (r"/", MainHandler),])if __name__ == "__main__":    application.listen(8888)    tornado.ioloop.IOLoop.instance().start()
