Django / FastAPI

What you'll learn

• Choose between Django and FastAPI for a Python web project and set up either.
• Build FastAPI endpoints with typed parameters, Pydantic validation, response models, dependencies and error handlers.
• Model data with the Django ORM, create migrations, and write efficient queries without N+1 problems.
• Use Django views, URLs, forms, transactions and password hashing correctly.
• Test both frameworks with their test clients and dependency overrides.
• Harden and deploy Python web apps with security checks and ASGI/WSGI servers.
