This video is a FastAPI tutorial for absolute beginners. We'll code along with the home page of the FastAPI docs, in the getting started tutorial section.

FastAPI is a modern and fast web framework for building APIs with Python. It has gained popularity due to its speed and ease of use, making it an ideal choice for building scalable and robust APIs. In this beginner FastAPI Python Tutorial, you will learn the basics of FastAPI.

FastAPI is one of the fastest Python frameworks available, and its syntax is easy to use, making it a great choice for building high-performance APIs. In this article, we will provide an introduction to FastAPI, including its features, advantages, and how it compares to other popular Python frameworks like Flask.

Features of FastAPI:

High Performance: FastAPI is built on top of the Starlette framework and uses the ASGI server, which is a high-performance web server. This makes FastAPI one of the fastest Python web frameworks available.

Easy to use: FastAPI provides a simple and intuitive API that makes it easy to build and maintain your API. Its syntax is similar to Flask, so if you are familiar with Flask, you should have no problem getting started with FastAPI.

Automatic Validation: FastAPI provides automatic validation of request data using Pydantic, which is a powerful data validation library for Python. This helps to ensure that the data being passed to your API is valid and of the correct type.

Dependency Injection: FastAPI provides support for dependency injection, which allows you to easily inject dependencies into your functions. This makes it easy to write modular and testable code.

Data Serialization: FastAPI provides high-performance data serialization using the built-in JSON and MessagePack libraries. This makes it easy to serialize and deserialize data for your API.

Advantages of FastAPI:

Speed: FastAPI is one of the fastest Python web frameworks available, making it an excellent choice for building high-performance APIs.

Easy to use: FastAPI has a simple and intuitive API, making it easy to build and maintain your API.

Automatic Validation: FastAPI provides automatic validation of request data, which helps to ensure that the data being passed to your API is valid and of the correct type.

Dependency Injection: FastAPI provides support for dependency injection, which makes it easy to write modular and testable code.

Scalability: FastAPI is built on top of ASGI, which makes it easy to scale your application to handle large numbers of requests.

FastAPI vs Flask:

Flask is one of the most popular Python web frameworks, and it has been around for a long time. Flask is a micro web framework that is easy to use and has a small footprint. FastAPI, on the other hand, is a modern web framework that is built on top of Starlette and provides many advanced features.

FastAPI is faster than Flask and provides automatic validation of request data and support for dependency injection, which Flask does not provide. Flask is easier to use and has a larger community, which means that it is easier to find resources and documentation for Flask.

FastAPI Tutorial:

If you are new to FastAPI and want to get started, there are many tutorials available online. A great place to start is the official FastAPI tutorial, which is available on the FastAPI website.
