Tornado is a scalable, non-blocking web server and web application framework written in Python. [2] It was developed for use by FriendFeed; the company was acquired by Facebook in 2009 and Tornado was open-sourced soon after. [3]
Tornado is noted for its high performance. Its design enables handling a large number of concurrent connections (i.e., tries to solve the " C10k problem").
The following code shows a simple web application that displays " Hello World!" when visited: [4]
import asyncio
import tornado.web
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())
