例えば、以下のような`main.py`ファイルを用意します:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

<a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> の第2引数は、デフォルトで返される値を指定します。

この引数を省略するとデフォルト値として`None`が返されますが、ここではデフォルト値として`"World"`を指定しています。

///

以下のようなものの1つ:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...さらによりエキゾチックなもの:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

HTTPプロトコルでは、これらの「メソッド」の1つ（または複数）を使用して各パスにアクセスできます。

---

APIを構築するときは、通常、これらの特定のHTTPメソッドを使用して特定のアクションを実行します。

通常は次を使用します:

* `POST`: データの作成
* `GET`: データの読み取り
* `PUT`: データの更新
* `DELETE`: データの削除

したがって、OpenAPIでは、各HTTPメソッドは「オペレーション」と呼ばれます。
