What are Python FastAPI, Flask, and Django?

Python FastAPI, Flask, and Django are popular web frameworks used for building web applications and APIs in Python. Flask is a lightweight, micro web framework that's easy to get started with and highly extensible. Django is a high-level, full-stack framework that provides many built-in features for rapid development, including an ORM and admin panel. FastAPI is a modern, fast (high-performance) framework designed for building APIs with automatic documentation and support for asynchronous programming. Each framework has its strengths, and the choice depends on the project's specific requirements.
