What is Django?

What is Django?

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It handles much of the hassle of web development so you can focus on writing your app.

Why Django?

• Batteries included — authentication, admin panel, ORM, form handling, and more come built-in
• Fast development — build applications quickly with less code
• Secure — protects against SQL injection, XSS, CSRF, and clickjacking out of the box
• Scalable — Instagram, Pinterest, and Mozilla use Django
• Python — clean, readable syntax that is great for beginners and professionals

The MVT Pattern

Django follows the Model-View-Template (MVT) architecture:

Component	Purpose	Similar To (MVC)
Model	Defines the data structure — database tables	Model
View	Handles business logic — processes requests, returns responses	Controller
Template	The HTML presentation layer — what the user sees	View

Request Flow

Browser sends request
    ↓
URL dispatcher matches a URL pattern
    ↓
View function is called
    ↓
View queries the Model (database)
    ↓
View passes data to a Template
    ↓
Template renders HTML
    ↓
Response sent back to browser
