### Evitar colisiones de nombres { #avoid-name-collisions }

Estamos importando el submódulo `items` directamente, en lugar de importar solo su variable `router`.

Esto se debe a que también tenemos otra variable llamada `router` en el submódulo `users`.

```

第二種是「絕對匯入」：

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

想了解更多關於 Python 套件與模組，請閱讀[官方的模組說明文件](https://docs.python.org/3/tutorial/modules.html)。

///

### 避免名稱衝突 { #avoid-name-collisions }

我們直接匯入子模組 `items`，而不是只匯入它的變數 `router`。

這是因為在子模組 `users` 中也有另一個名為 `router` 的變數。

如果我們像下面這樣一個接一個匯入：

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

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

### 이름 충돌 피하기 { #avoid-name-collisions }

submodule `items`를 직접 import하고, 그 안의 `router` 변수만 import하지는 않습니다.

이는 submodule `users`에도 `router`라는 이름의 변수가 있기 때문입니다.

만약 다음처럼 순서대로 import했다면:

```Python
from .routers.items import router

```

### 名前衝突の回避 { #avoid-name-collisions }

サブモジュール `items` の変数 `router` だけをインポートするのではなく、サブモジュール自体を直接インポートしています。

これは、サブモジュール `users` にも `router` という変数があるためです。

もし次のように続けてインポートした場合:

```Python
from .routers.items import router

Data encryption keys are still randomly generated on server start but an atomic counter is used to prevent nonce collisions.
