これは、Pythonの関数です。

この関数は、`GET`オペレーションを使ったURL「`/`」へのリクエストを受け取るたびに**FastAPI**によって呼び出されます。

この場合、この関数は`async`関数です。

---

`async def`の代わりに通常の関数として定義することもできます:

```Python hl_lines="7"
{!../../docs_src/first_steps/tutorial003.py!}
```

/// note | "備考"

違いが分からない場合は、[Async: *"急いでいますか？"*](../async.md#_1){.internal-link target=_blank}を確認してください。

///

### Step 5: コンテンツの返信

In this case, it is an `async` function.

---

You could also define it as a normal function instead of `async def`:

{* ../../docs_src/first_steps/tutorial003.py hl[7] *}

/// note

If you don't know the difference, check the [Async: *"In a hurry?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

///
