120: FastAPI & Typer - Sebastián Ramírez
FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints.
Typer is a library for building CLI applications, also based on Python type hints.
Type hints and many other details are intended to make it easier to develop, test, and debug applications using FastAPI and Typer.
