#### `Tuple` et `Set`

C'est le même fonctionnement pour déclarer un `tuple` ou un `set` :

{*../../docs_src/python_types/tutorial007.py hl[1,4] *}

Dans cet exemple :

* La variable `items_t` est un `tuple` avec 3 éléments, un `int`, un deuxième `int`, et un `str`.
* La variable `items_s` est un `set`, et chacun de ses éléments est de type `bytes`.

#### `Dict`

## Set 类型

但是随后我们考虑了一下，意识到标签不应该重复，它们很大可能会是唯一的字符串。

Python 具有一种特殊的数据类型来保存一组唯一的元素，即 `set`。

然后我们可以导入 `Set` 并将 `tag` 声明为一个由 `str` 组成的 `set`：
