Python - FastAPI

FastAPI is a modern and fast web development framework for Python that allows you to create APIs easily, quickly, and with outstanding performance. It stands out for its speed, ease of use, and automatic generation of interactive documentation.

Some of its key features are:

1. Speed: It uses Python's static typing system to achieve exceptional performance through compilation and static validation at runtime.

2. Easy to use: It is based on Python-like annotations (using Pydantic) to define data types, making data validation and request/response handling easier.

3. Automatic documentation generation: It has a self-generated interactive documentation system (OpenAPI/Swagger) based on defined types and method annotations.

4. Asynchronous compatibility: It allows handling asynchronous operations, making it ideal for high-performance web applications.

5. Support for web standards: It supports authentication, authorization, web sockets, file uploading, among other web standards.

FastAPI is built on the architecture of Starlette and Pydantic, leveraging the advantages of both to provide a fast, modern, and highly efficient development framework for creating APIs in Python. Additionally, by leveraging Python's static typing system capabilities, it offers strong static validation that helps prevent errors before they occur during runtime.

In summary, FastAPI is a powerful tool for developing APIs with Python, standing out for its performance, ease of use, and automatic documentation generation, making it a popular choice for projects that require fast, secure, and well-documented APIs.
