* **ścieżka**: to `/`.
* **operacja**: to `get`.
* **funkcja**: to funkcja poniżej "dekoratora" (poniżej `@app.get("/")`).

{* ../../docs_src/first_steps/tutorial001.py hl[7] *}

Jest to funkcja Python.

Zostanie ona wywołana przez **FastAPI** za każdym razem, gdy otrzyma żądanie do adresu URL "`/`" przy użyciu operacji `GET`.

W tym przypadku jest to funkcja "asynchroniczna".
