Поэтому мы используем относительный импорт с `..` для зависимостей:

#### Как работает относительный импорт { #how-relative-imports-work }

/// tip | Подсказка

Если вы прекрасно знаете, как работает импорт, переходите к следующему разделу ниже.

///

Одна точка `.`, как здесь:

```Python

    ```bash
    bazel run //tensorflow/tools/docs:tf_doctest
    ```

    or

    ```bash
    bazel run //tensorflow/tools/docs:tf_doctest -- --module=ops.array_ops
    ```

    The `--module` is relative to `tensorflow.python`.

#### Debug builds

When [building Tensorflow](https://www.tensorflow.org/install/source), passing
`--config=dbg` to Bazel will build with debugging information and without

我們需要從模組 `app.dependencies`（檔案 `app/dependencies.py`）取得相依性函式。

因此我們用 `..` 做相對匯入相依性：

{* ../../docs_src/bigger_applications/app_an_py310/routers/items.py hl[3] title["app/routers/items.py"] *}

#### 相對匯入如何運作 { #how-relative-imports-work }

如果你對匯入的運作方式十分了解，可以直接跳到下一節。

單一的點號 `.`，如下：

```Python
from .dependencies import get_token_header
```

```
### Beispiel { #example }
```

### Links

Use the following rules for links (apply both to Markdown-style links ([text](url)) and to HTML-style <a href="url">text</a> tags):

- For relative URLs, only translate the link text. Do not translate the URL or its parts.

Example:

Source (English):

```
[One of the fastest Python frameworks available](#performance)
```
