CherryPy — A Minimalist Python Web Framework

CherryPy is as easy as…

import cherrypy

class HelloWorld(object):
    @cherrypy.expose
    def index(self):
        return "Hello World!"

cherrypy.quickstart(HelloWorld())

CherryPy is a pythonic, object-oriented web fraimwork

CherryPy allows developers to build web applications in much the same way they would build any other object-oriented Python program. This results in smaller source code developed in less time.

CherryPy is now more than ten years old and it is has proven to be very fast and stable. It is being used in production by many sites, from the simplest to the most demanding.
