#### 🔢 & ⚒

👆 🔜 🎏 📣 `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`.

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`.

| ...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.

pkg go/types, method (*Struct) Tag(int) string
pkg go/types, method (*Struct) Underlying() Type
pkg go/types, method (*Tuple) At(int) *Var
pkg go/types, method (*Tuple) Len() int
pkg go/types, method (*Tuple) String() string
pkg go/types, method (*Tuple) Underlying() Type
pkg go/types, method (*TypeName) Exported() bool
pkg go/types, method (*TypeName) Id() string
pkg go/types, method (*TypeName) Name() string

pkg go/types, func Instantiate(*Context, Type, []Type, bool) (Type, error)
pkg go/types, func NewContext() *Context
pkg go/types, func NewSignature //deprecated
pkg go/types, func NewSignatureType(*Var, []*TypeParam, []*TypeParam, *Tuple, *Tuple, bool) *Signature
pkg go/types, func NewTerm(bool, Type) *Term

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

    এবং Python 3.8 এর মতোই, `typing` মডিউল থেকে:

    * `Union`
    * `Optional`
    * ...এবং অন্যান্য।

=== "Python 3.8+"

    * `List`
    * `Tuple`
    * `Set`
    * `Dict`
    * `Union`
    * `Optional`
    * ...এবং অন্যান্য।

注意，变量 `item` 是列表 `items` 中的元素之一。

而且，编辑器仍然知道它是一个 `str`，并为此提供了支持。

#### 元组和集合

声明 `tuple` 和 `set` 的方法也是一样的：

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

这表示：

* 变量 `items_t` 是一个 `tuple`，其中的前两个元素都是 `int` 类型, 最后一个元素是 `str` 类型。
* 变量 `items_s` 是一个 `set`，其中的每个元素都是 `bytes` 类型。

#### 字典

定义 `dict` 时，需要传入两个子类型，用逗号进行分隔。

  // List of MutatingWebhookConfiguration.
  repeated MutatingWebhookConfiguration items = 2;
}

// Rule is a tuple of APIGroups, APIVersion, and Resources.It is recommended
// to make sure that all the tuple expansions are valid.
message Rule {
  // APIGroups is the API groups the resources belong to. '*' is all groups.
  // If '*' is present, the length of the slice must be one.

}

// NamedRuleWithOperations is a tuple of Operations and Resources with ResourceNames.
// +structType=atomic
message NamedRuleWithOperations {
  // ResourceNames is an optional white list of names that the rule applies to.  An empty set means that everything is allowed.
  // +listType=atomic
  // +optional
  repeated string resourceNames = 1;

  // RuleWithOperations is a tuple of Operations and Resources.

### Declare a `List` com um parâmetro de tipo

Para declarar tipos que têm parâmetros de tipo(tipos internos), como `list`, `dict`, `tuple`:

* Importe os do modulo `typing`
* Passe o(s) tipo(s) interno(s) como "parâmetros de tipo" usando colchetes: `[` e `]`

```Python
from typing import List

my_list: List[str]
```
