Question

I just started learning Tornado and bumped into the first problem in my hello.py.
I followed the steps and codes given by “Introduction to Tornado”. Here is the code.

     import tornado.httpserver
     import tornado.ioloop
     import tornado.options
     import tornado.web

     from tornado.options import define, options
     define("port", default=8000, help="run on the given port", type=int)

     class IndexHandler(tornado.web.RequestHandler):
         def get(self):
            greeting = self.get_argument('greeting','Hello')
            self.write(greeting + ', friendly user!')

     if __name__=="__main__":
        tornado.options.parse_command_line()
        app = tornado.web.Application(handers=[(r"/", IndexHandler)])
        http_server = tornado.httpserver.HTTPServer(app)
        http_server.listen(options.port)
        tornado.ioloop.IOLoop.instance().start()

after I run it in other Terminal window by

    curl http://localhost:8000/

I didn’t get the expected answer, which should be

    Hello, friendly user! 

Instead, the respond is something like

    [I 121026 18:20:38 web:1359] 301 GET / (127.0.0.1) 1.12ms

I am so new to this that I have no idea how to solve it. The problem may sound really stupid buy please do me a favor and help me out! Thanks lot!!!!!

Not sure if it is the primary issue, but you misspelled handlers in

handers=[(r"/", IndexHandler)])
