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"
{!> ../../docs_src/body_nested_models/tutorial002.py!}
```

### 声明具有子类型的 List

要声明具有子类型的类型，例如 `list`、`dict`、`tuple`：

* 从 `typing` 模块导入它们
* 使用方括号 `[` 和 `]` 将子类型作为「类型参数」传入

```Python
from typing import List

my_list: List[str]
```

这完全是用于类型声明的标准 Python 语法。

        final List<WebConfig> webConfigList;
        if (runAll || webConfigIdList != null) {
