How to use the Tornado framework in Python

Tornado is a Python web framework and asynchronous networking library. It is designed to handle large amounts of traffic and offers high performance and scalability. To use Tornado, you need to install it first. You can do this using pip:

pip install tornado

Once installed, you can use the Tornado framework in your Python application. To create a web application, you will need to create a Tornado application object. This object will contain the application logic and handle requests. You can also define routes and handlers for the application.

For example, you can create a basic Hello World application using the following code:

import tornado.ioloop import tornado.web class MainHandler(tornado.web.RequestHandler): def get(self): self.write(“Hello, world”) application = tornado.web.Application([ (r”/”, MainHandler), ]) if __name__ == “__main__”: application.listen(8888) tornado.ioloop.IOLoop.current().start()

This code creates a web application that responds to requests on the root path (/) with the message “Hello, world”.

Tornado also has a wide range of features such as template engines, authentication, and web sockets. For more information, please see the official Tornado documentation.
