CherryPy also known as a web application library is a Python web framework that provides a friendly interface to the HTTP protocol for Python developers. It allows developers to build web applications the same way as in traditional object-oriented Python programs. Thereby, resulting in smaller source code developed in no time.
This framework is mainly for the developers who want to create a portable database-driven web application using Python, as it provides Create, Retrieve, Update, and Delete functionalities.
The basic requirements for the installation of CherryPy include:
- Python with version 2.4 or above
- Cherrypy 3.0
To install cherrypy run the following command in terminal:
pip install cherrypy
Approach:
- Create a user interface to take input from the user.
- Write cherrypy program to perform required operations
HTML code to create a user interface to take input from the user:
HTML
<html> Â Â Â <body>Â Â Â Â Â Â Â <div class="container">Â Â Â Â Â Â Â <h2><u><i>Operation</i></u></h2>Â Â Â Â Â <form action="store" id="form" method="GET">Â Â Â Â Â <input type="number" name="number1" /><br />Â Â Â Â Â <input type="number" name="number2" /><br />Â Â Â Â Â Â Â Â Â Â Â Â Â <input style="margin-left: 250px;" id=" submit" type="submit"/></div>Â Â Â </div>Â Â Â Â Â Â Â Â Â </form>Â Â Â </div>Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â </body>Â </html> |
Cherrypy code for multiplication
Python3
import cherrypy     class Root(object):       @cherrypy.expose     def index(self):         return """<html> <head>   </head> <body>   <div class="container">     <h2><u><i>Multiplication</i></u></h2>     <form action="store" id="form" method="GET">     <input type="number" name="num1" /><br />     <input type="number" name="num2" /><br />         <input style="margin-left: 250px;" id=" submit" type="submit"/></div> </div>     </form> </div>   </body> </html>"""      @cherrypy.expose     def store(self, num1, num2):           mul1 = int(num1)         mul2 = int(num2)           result = mul1*mul2           out = """<html>         <body>                       <p> Sum: %s</p>                                  <a style="color:red; font-size:35px;" id="shutdown"; href="./shutdown"><i>Shutdown Server</i></a>         </body>         </html>                   """          return out % (result)       @cherrypy.expose     def shutdown(self):         cherrypy.engine.exit()     if __name__ == "__main__":     cherrypy.config.update({'server.socket_port': 8087})       cherrypy.quickstart(Root()) |
Output:
