A well-structured repository covering Django, Flask, and REST APIs — built for learning, revision, and practical viva preparation.
This repo focuses on core backend concepts, clear explanations, and exam-ready clarity.

• Django – Full-featured Python web framework
• Flask – Lightweight micro web framework
• REST API – Stateless backend communication standard

Django is a high-level Python web framework that follows the MVT (Model–View–Template) architecture and enables rapid development of secure, scalable, database-driven web applications.

• Model → Database layer (ORM)
• View → Business logic & request handling
• Template → Presentation layer (HTML)

• Built-in ORM
• Admin panel
• Authentication & authorization
• Security (CSRF, XSS, SQL injection protection)
• Rapid development

• models.py → Database schema
• views.py → Application logic
• urls.py → URL routing
• settings.py → Project configuration
• manage.py → Command-line utility

• makemigrations → Create migration files
• migrate → Apply changes to database

Flask is a lightweight (micro) Python web framework used to build web applications and REST APIs.

Flask provides only core features like routing and request handling.
Additional functionality is added using extensions.

• @app.route() → URL routing
• View functions → Handle requests
• render_template() → Render HTML templates
• request → Client request data
• jsonify() → JSON responses
• Jinja2 → Template engine

• Simple and flexible
• Easy to learn
• Ideal for APIs and small to medium projects

• No built-in ORM
• No admin panel
• Requires manual structure and security setup

API (Application Programming Interface) allows communication between two applications.

REST (Representational State Transfer) is an architectural style that uses HTTP to manage resources.

A REST API uses HTTP methods to perform operations on resources in a stateless manner.

• Stateless
• Client-server architecture
• Uses JSON for data exchange

• Django → Django REST Framework (DRF)
• Flask → Flask routes + jsonify() / Flask-RESTful

• Django follows MVC ❌
• Flask follows MVT ❌
• REST is a protocol ❌
• GET modifies data ❌
• Flask has built-in admin ❌

• Django is structured and full-featured
• Flask is flexible and minimal
• REST APIs are stateless and resource-based
• Django + Flask + REST form a strong backend foundation

• B.Tech / MCA students
• Backend beginners
• Django & Flask learners
• Practical viva preparation
• Revision before exams or interviews
