`items` 模块将具有一个 `router` 变量（`items.router`）。这与我们在 `app/routers/items.py` 文件中创建的变量相同，它是一个 `APIRouter` 对象。

然后我们对 `users` 模块进行相同的操作。

我们也可以像这样导入它们：

```Python
from app.routers import items, users
```

/// info | 信息

第一个版本是「相对导入」：

```Python
from .routers import items, users
```

第二个版本是「绝对导入」：

```Python
from app.routers import items, users
```
