Đây là "**hàm cho đường dẫn toán tử**":

* **đường dẫn**: là `/`.
* **toán tử**: là `get`.
* **hàm**: là hàm bên dưới "decorator" (bên dưới `@app.get("/")`).

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

Đây là một hàm Python.

Nó sẽ được gọi bởi **FastAPI** bất cứ khi nào nó nhận một request tới URL "`/`" sử dụng một toán tử `GET`.

Trong trường hợp này, nó là một hàm `async`.
