由于文件 `app/routers/users.py` 和 `app/routers/items.py` 是同一 Python 包 `app` 一个部分的子模块，因此我们可以使用单个点 ` .` 通过「相对导入」来导入它们。

### 导入是如何工作的 { #how-the-importing-works }

这段代码：

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

表示：

* 从该模块（`app/main.py` 文件）所在的同一个包（`app/` 目录）开始...
* 寻找 `routers` 子包（位于 `app/routers/` 的目录）...

        resp = new SmbComReadAndXResponse();

        connect0();
        dest.connect0();

        /* At this point the maxBufferSize values are from the server
         * exporting the volumes, not the one that we will actually
         * end up performing IO with. If the server hosting the
         * actual files has a smaller maxBufSize this could be

# There is ongoing work on Bazel team's side to provide support for transitive
# shared libraries. As part of migrating to transitive shared libraries, we
# hope to provide a better mechanism for control over symbol exporting, and
# then tackle this issue again.

`app/routers/users.py` と `app/routers/items.py` は同じ Python パッケージ `app` のサブモジュールなので、1つのドット `.` を使った「相対インポート」でインポートできます。

### インポートの動作 { #how-the-importing-works }

次の部分:

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

は次の意味です:

* このモジュール（`app/main.py`）が存在する同じパッケージ（ディレクトリ `app/`）から開始し...
* サブパッケージ `routers`（ディレクトリ `app/routers/`）を探し...

// containsRune is a simplified version of strings.ContainsRune
// to avoid importing the strings package.
// We avoid bytes.ContainsRune to avoid allocating a temporary copy of s.
func containsRune(s string, r rune) bool {
	for _, c := range s {
		if c == r {
			return true
		}
	}
