## バックグラウンドタスクの追加

*path operations 関数* 内で、`.add_task()` メソッドを使用してタスク関数を *background tasks* オブジェクトに渡します。

```Python hl_lines="14"
{!../../../docs_src/background_tasks/tutorial001.py!}
```

`.add_task()` は以下の引数を受け取ります:

* バックグラウンドで実行されるタスク関数 (`write_notification`)。
* タスク関数に順番に渡す必要のある引数の列 (`email`)。

{!../../../docs_src/background_tasks/tutorial001.py!}
```

## Add the background task

Inside of your *path operation function*, pass your task function to the *background tasks* object with the method `.add_task()`:

```Python hl_lines="14"
{!../../../docs_src/background_tasks/tutorial001.py!}
```

`.add_task()` receives as arguments:

* A task function to be run in the background (`write_notification`).

`assemble` — _lifecycle task_::
Plugins and build authors should attach tasks that produce distributions and other consumable artifacts to this lifecycle task. For example, `jar` produces the consumable artifact for Java libraries. Attach tasks to this lifecycle task using `assemble.dependsOn(__task__)`.

`build` — _lifecycle task_::
_Depends on_: `check`, `assemble`
