Chú ý rằng, biến `item` là một trong các phần tử trong danh sách `items`.

Và do vậy, trình soạn thảo biết nó là một `str`, và cung cấp sự hỗ trợ cho nó.

#### Tuple and Set

Bạn sẽ làm điều tương tự để khai báo các `tuple` và  các `set`:

=== "Python 3.9+"

    ```Python hl_lines="1"
    {!> ../../../docs_src/python_types/tutorial007_py39.py!}
    ```

=== "Python 3.8+"

    * `list`
    * `tuple`
    * `set`
    * `dict`

    Verwenden Sie für den Rest, wie unter Python 3.8, das `typing`-Modul:

    * `Union`
    * `Optional`
    * ... und andere.

//
// The above means that any added/deleted fields are incompatible.
//
//msgp:tuple VolInfo
type VolInfo struct {
	// Name of the volume.
	Name string

	// Date and time when the volume was created.
	Created time.Time
}

// FilesInfo represent a list of files, additionally
// indicates if the list is last.
//
//msgp:tuple FileInfo
type FilesInfo struct {
	Files       []FileInfo
	IsTruncated bool
}

El editor aún sabe que es un `str` y provee soporte para ello.

#### Tuples y Sets

Harías lo mismo para declarar `tuple`s y `set`s:

```Python hl_lines="1  4"
{!../../../docs_src/python_types/tutorial007.py!}
```

Esto significa:

* La variable `items_t` es un `tuple` con 3 ítems, un `int`, otro `int`, y un `str`.

//msgp:marshal ignore dataUsageEntryV2 dataUsageEntryV3 dataUsageEntryV4 dataUsageEntryV5 dataUsageEntryV6 dataUsageEntryV7

//msgp:tuple dataUsageEntryV2
type dataUsageEntryV2 struct {
	// These fields do no include any children.
	Size     int64
	Objects  uint64
	ObjSizes sizeHistogram
	Children dataUsageHashMap
}

//msgp:tuple dataUsageEntryV3
type dataUsageEntryV3 struct {
	// These fields do no include any children.

| ...header_n     | msgp bin array              | Header of last version
| ...metadata_n   | msgp bin array              | Metadata of last version

Each header contains a mspg array (tuple) encoded object:

xlHeaderVersion version == 1:

```
//msgp:tuple xlMetaV2VersionHeader
type xlMetaV2VersionHeader struct {
 VersionID [16]byte  // Version UUID, raw.
 ModTime   int64     // Unix nanoseconds.

#### 🔢 & ⚒

👆 🔜 🎏 📣 `tuple`Ⓜ & `set`Ⓜ:

=== "🐍 3️⃣.6️⃣ & 🔛"

    ```Python hl_lines="1  4"
    {!> ../../../docs_src/python_types/tutorial007.py!}
    ```

=== "🐍 3️⃣.9️⃣ & 🔛"

    ```Python hl_lines="1"
    {!> ../../../docs_src/python_types/tutorial007_py39.py!}
    ```

👉 ⛓:

* 🔢 `items_t` `tuple` ⏮️ 3️⃣ 🏬, `int`, ➕1️⃣ `int`, & `str`.

        # Store the path to be able to re-generate a dependable from it in overrides
        self.path = path
        # Save the cache key at creation to optimize performance

タイプがなければ、それはほぼ不可能です。

変数`item`はリスト`items`の要素の一つであることに注意してください。

それでも、エディタはそれが`str`であることを知っていて、そのためのサポートを提供しています。

#### `Tuple` と `Set`

`tuple`と`set`の宣言も同様です:

```Python hl_lines="1 4"
{!../../../docs_src/python_types/tutorial007.py!}
```

つまり:

* 変数`items_t`は`int`、`int`、`str`の3つの項目を持つ`tuple`です

* 変数`items_s`はそれぞれの項目が`bytes`型である`set`です。

#### `Dict`

`dict`を宣言するためには、カンマ区切りで2つの型パラメータを渡します。
