Once the task is assigned to a group, it will be listed by `./gradlew tasks`:

$ ./gradlew tasks

> Task :tasks

Custom tasks
------------------
hello - A lovely greeting task.
----

To view information about a task, use the `help --task <task-name>` command:

[source]

  // Pack 3 variable handles into one TFE_TensorHandle.
  // When remote is false, function device is placed on task0. Handle types are
  // REMOTE, REMOTE, LOCAL on task0. When remote is true, function device is
  // placed on task1, Handle types are LOCAL, REMOTE, LOCAL on task1.
  int num_replicas = 3;
  std::vector<TFE_TensorHandle*> handles = {h0, h1, h2};
  TFE_TensorHandle* packed_handle =

func UserTasksHandlerFunc(t *parsedTrace) http.HandlerFunc {
	return func(w http.ResponseWriter, r *http.Request) {
		tasks := t.summary.Tasks

		// Summarize groups of tasks with the same name.
		summary := make(map[string]taskStats)
		for _, task := range tasks {
			stats, ok := summary[task.Name]
			if !ok {
				stats.Type = task.Name
			}
			stats.add(task)

So if you only run `taskY` with `mustRunAfter`, you won't cause `taskX` to run.
This is expressed as `taskY.mustRunAfter(taskX)`.

## 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`).
