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

"method","promise","fail","then","Callbacks","object","_","flag","firing","memory","fired","locked","list","queue","firingIndex","fire","once","stopOnFalse","remove","disable","lock","fireWith","Deferred","func","tuples","state","always","deferred","catch","pipe","fns","newDefer","tuple","returned","progress","notify","onFulfilled","onRejected","onProgress","maxDepth","depth","handler","special","that","mightThrow","TypeError","notifyWith","resolveWith","process","exceptionHook","rejectWith","ge...

没有类型，几乎是不可能实现下面这样：

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。

### Generic types with type parameters

There are some data structures that can contain other values, like `dict`, `list`, `set` and `tuple`. And the internal values can have their own type too.

These types that have internal types are called "**generic**" types. And it's possible to declare them, even with their internal types.

Đa phần đều không thể đạt được nếu không có các kiểu dữ liệu.

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`:
