Code Less, Ship Faster: Building APIs with FastAPI

FastAPI is introduced as a high-performance Python framework for building APIs, positioned as a modern alternative to Django and Flask. The guide provides instructions for installation and setup within a virtual environment. It then demonstrates core concepts through two examples: a simple "Hello World" application and a more complex to-do list API that showcases CRUD operations, data validation using Pydantic models, and error handling. A key feature highlighted is the automatic, interactive API documentation generated via Swagger UI, which allows for easy testing of endpoints.
