How to perform multiplication using CherryPy in Python?

0 0 1 minute read

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> 
   
<body>  
    
  <div class="container">    
    <h2><u><i>Operation</i></u></h2>  
    <form action="store" id="form" method="GET">  
    <input type="number" name="number1" /><br />  
    <input type="number" name="number2" /><br />  
    
    
    <input style="margin-left: 250px;" id=" submit" type="submit"/></div>  
  </div>      
    </form>  
  </div>  
                
</body>  
</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())
