`Tornado `_ is a Python web framework and

asynchronous networking library, originally developed at `FriendFeed

`_.  By using non-blocking network I/O, Tornado

can scale to tens of thousands of open connections, making it ideal for

`long polling `_,

`WebSockets `_, 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

`_.
