`Tornado <http://www.tornadoweb.org>`_ is a Python web framework and
asynchronous networking library, originally developed at `FriendFeed
<http://friendfeed.com>`_.  By using non-blocking network I/O, Tornado
can scale to tens of thousands of open connections, making it ideal for
`long polling <http://en.wikipedia.org/wiki/Push_technology#Long_Polling>`_,
`WebSockets <http://en.wikipedia.org/wiki/WebSocket>`_, and other
applications that require a long-lived connection to each user.

Hello, world
------------

Here is a simple "Hello, world" example web app for Tornado:

.. code-block:: python

    import asyncio
    import tornado

    class MainHandler(tornado.web.RequestHandler):
        def get(self):
            self.write("Hello, world")

    def make_app():
        return tornado.web.Application([
            (r"/", MainHandler),
        ])

    async def main():
        app = make_app()
        app.listen(8888)
        await asyncio.Event().wait()

    if __name__ == "__main__":
        asyncio.run(main())

This example does not use any of Tornado's asynchronous features; for
that see this `simple chat room
<https://github.com/tornadoweb/tornado/tree/stable/demos/chat>`_.
