Tutorial 1: Let’s start with stem of the cherrypy

Building Basic Web Application

The most straightforward application you might create with CherryPy is shown in the example below. When a request reaches http://127.0.0.1:8080/, a server is started, and an application is hosted there.

Code:

import cherrypy
class HelloWorld(object):
    @cherrypy.expose
    def index(self):
        return "Hey Ninja!! This is Your First Application."
if __name__ == '__main__':
    cherrypy.quickstart(HelloWorld())

Explanation:

This reveals a number of things. The server will conduct signal handling for you according to the first three lines. The server is now in the starting stage, as indicated by the information in the following line. You are then informed that no particular configuration has been set for your application. The server then launches a few internal tools, which we will go over in more detail later. The server now listens on IP 127.0.0.1:8080, indicating that it is ready to receive inbound communications. In other words, your application is now prepared for use.
Let's talk about the message about the lack of configuration before continuing. As soon as you configure CherryPy, a feature will automatically check the application's settings for correct syntax. Thus, a warning message is shown in the logs when none are provided. That log is innocuous and won't interfere with CherryPy's functionality.

Frequently Asked Questions

Is CherryPy open source?

Yes, CherryPy is an open-source project. If you're interested, you may fork CherryPy on GitHub here and send a pull request with your changes.

Is CherryPy a Web server?

CherryPy can be used as a standalone web server or in conjunction with any WSGI-compatible environment. It doesn't deal with things like output rendering templates or backend access. Filters can be added to the framework and are invoked at specific times throughout the processing of requests and responses.

What is CherryPy used for?

CherryPy wraps the HTTP protocol and is intended to speed up the creation of web applications.
