*I installed tornado and he is functional, but when I execute the following
script:*

import tornado.ioloop
import tornado.web
import cgi

class MainHandler(tornado.web.
RequestHandler):

    form = cgi.FieldStorage()                 # parse form data
    print('Content-type: text/html\n')        # hdr plus blank line
    print('<title>Reply Page</title>')        # html reply page
    if not 'user' in form:
            print('<h1>Who are you?</h1>')
    else:
            print('<h1>Hello <i>%s</i>!</h1>' %
cgi.escape(form['user'].value))

application = tornado.web.Application([
    (r"/", MainHandler),
])

if __name__ == "__main__":
    application.listen(8888)
    tornado.ioloop.IOLoop.instance().start()

*In the terminal have these outputs:*

python test.py
Content-type: text/html

<title>Reply Page</title>
<h1>Who are you?</h1>

*When I call the browser on localhost:8888, the message is this:*

405: Method Not Allowed
*
**Please, can someone have a idea about why the error occurs? and what I
need to do to fix this?*
