What is Django in Python?
Why Interviewers Ask This
This is a differentiating question used for senior and lead roles. Interviewers want to see if you can explain not just what happens, but why — and what the trade-offs are in different approaches.
Answer
Django is Python's most popular full-stack web framework, following the "batteries included" philosophy. It provides: ORM (Django ORM with migrations), admin interface (automatic CRUD UI from models), URL routing, template engine, forms with validation, authentication system (users, groups, permissions), security (CSRF, XSS, SQL injection protection built-in). Project structure: django-admin startproject mysite, python manage.py startapp blog. Define models, create migrations (manage.py makemigrations/migrate), define views (function-based or class-based), configure URLs. Django REST Framework (DRF) adds API serialization. Django channels adds WebSocket support. Django follows MTV (Model-Template-View) which is effectively MVC. Its convention-over-configuration approach means fast development for standard web apps.
Common Mistake
Don't just define the term — demonstrate that you understand when to use it and when not to. Showing awareness of trade-offs is what separates average from strong Python candidates.
