### 🚮 🛃 `tags`, `responses`, & `dependencies`

👥 🚫 ❎ 🔡 `/items` 🚫 `tags=["items"]` 🔠 *➡ 🛠️* ↩️ 👥 🚮 👫 `APIRouter`.

✋️ 👥 💪 🚮 _🌅_ `tags` 👈 🔜 ✔ 🎯 *➡ 🛠️*, & ➕ `responses` 🎯 👈 *➡ 🛠️*:

```Python hl_lines="30-31" title="app/routers/items.py"

    {!> ../../../docs_src/body_nested_models/tutorial001_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="14"
    {!> ../../../docs_src/body_nested_models/tutorial001.py!}
    ```

这将使 `tags` 成为一个由元素组成的列表。不过它没有声明每个元素的类型。

## 具有子类型的 List 字段

但是 Python 有一种特定的方法来声明具有子类型的列表：

### 从 typing 导入 `List`

首先，从 Python 的标准库 `typing` 模块中导入 `List`：

```Python hl_lines="1"
