你可以将一个属性定义为一个子类型。例如，Python `list`：

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

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。

## 带类型参数的 List 字段 { #list-fields-with-type-parameter }

不过，Python 有一种用于声明具有内部类型（类型参数）的列表的特定方式：

### 声明带类型参数的 `list` { #declare-a-list-with-a-type-parameter }

要声明具有类型参数（内部类型）的类型，例如 `list`、`dict`、`tuple`，使用方括号 `[` 和 `]` 传入内部类型作为「类型参数」：

```Python
my_list: list[str]
```

这完全是用于类型声明的标准 Python 语法。
