Passen Sie dann den Uvicorn-Befehl an, um das neue Modul `main` anstelle von `app.main` zu verwenden, um das FastAPI-Objekt `app` zu importieren.

By declaring types for your variables, editors and tools can give you better support.

This is just a **quick tutorial / refresher** about Python type hints. It covers only the minimum necessary to use them with **FastAPI**... which is actually very little.

**FastAPI** is all based on these type hints, they give it many advantages and benefits.
