FastAPI: A High-Performance Python Framework for Building APIs

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints. It's designed to be easy to use and provide high performance, making it a popular choice for building web applications and APIs. Some of its key features include:

• Fast: FastAPI is built on top of Starlette for the web parts and Pydantic for the data parts, both of which are very fast.
• Easy to use: FastAPI is designed to be easy to use, with clear and concise documentation, and a simple API for creating and deploying applications.
• Automatic validation: FastAPI automatically validates request data using Pydantic, making it easy to create APIs that are both fast and safe.
• Type hints: FastAPI uses Python's type hints to automatically generate documentation and provide autocomplete suggestions in popular IDEs.
• Async support: FastAPI is built using asynchronous code, which allows it to handle many requests at once and keep up with high traffic loads.
• Websockets: FastAPI provides built-in support for WebSockets, making it easy to build real-time applications such as chat rooms or live dashboards.

Overall, FastAPI is a powerful and flexible web framework that is well-suited to building high-performance APIs and web applications in Python.
