#### *パスオペレーションデコレータ*を定義

```Python hl_lines="6"
{!../../docs_src/first_steps/tutorial001.py!}
```
`@app.get("/")`は直下の関数が下記のリクエストの処理を担当することを**FastAPI**に伝えます:

* パス `/`
* <abbr title="an HTTP GET method"><code>get</code> オペレーション</abbr>

/// info | "`@decorator` について"

Pythonにおける`@something`シンタックスはデコレータと呼ばれます。

「デコレータ」は関数の上に置きます。かわいらしい装飾的な帽子のようです（この用語の由来はそこにあると思います）。

「デコレータ」は直下の関数を受け取り、それを使って何かを行います。

    for (int i = 0; i < elements.length; i++) {
      multimap.put(elements[i], i);
    }
  }

  /**

   * but the latest value for each key. This class exists only so that we can use {@link

 Logger name is basically the classical fully qualified class name: it's not visible by default, but can be activated (see {{{/maven-logging.html}user documentation}}).

 Notice that before Maven 3.1.0, with logger created by Maven, some code used to pass logger from class to class because it could not create a new logger:

Da die Testfunktion jetzt asynchron ist, können Sie in Ihren Tests neben dem Senden von Requests an Ihre FastAPI-Anwendung jetzt auch andere `async`hrone Funktionen aufrufen (und `await`en), genau so, wie Sie diese an anderer Stelle in Ihrem Code aufrufen würden.

/// tip | "Tipp"

As the testing function is now asynchronous, you can now also call (and `await`) other `async` functions apart from sending requests to your FastAPI application in your tests, exactly as you would call them anywhere else in your code.
