Design a Website for Server Side Processing

AIM:

To design a website to perform mathematical calculations in server side.

DESIGN STEPS:

Step 1:

clone the repositryfrom github

Step 2:

create Django Admin project

Step 3:

create a new app

Step 4:

create python programs for views and urls

Step 5:

create a HTML file of forms

Step 6:

Publish the website in the given URL.

PROGRAM :
