这将引用 `app/` 的往上一级，带有其自己的 `__init __.py` 等文件的某个包。但是我们并没有这个包。因此，这将在我们的示例中引发错误。🚨

但是现在你知道了它的工作原理，因此无论它们多么复杂，你都可以在自己的应用程序中使用相对导入。🤓

### 添加一些自定义的 `tags`、`responses` 和 `dependencies`

我们不打算在每个*路径操作*中添加前缀 `/items` 或 `tags =["items"]`，因为我们将它们添加到了 `APIRouter` 中。

但是我们仍然可以添加*更多*将会应用于特定的*路径操作*的 `tags`，以及一些特定于该*路径操作*的额外 `responses`：
