                      Down the Rabbit-Hole

由於 `app/routers/users.py` 與 `app/routers/items.py` 是同一個 Python 套件 `app` 的子模組，我們可以用單一的點號 `.` 來進行「相對匯入」。

### 匯入如何運作 { #how-the-importing-works }

這段：

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

代表：

* 從此模組（檔案 `app/main.py`）所在的相同套件（目錄 `app/`）開始...
* 尋找子套件 `routers`（目錄 `app/routers/`）...

		bucketName string
		shouldPass bool
	}{
		// cases which should pass the test.
		// passing in valid bucket names.
		{"lol", true},
		{"1-this-is-valid", true},
		{"1-this-too-is-valid-1", true},
		{"this.works.too.1", true},
		{"1234567", true},
		{"123", true},
		{"s3-eu-west-1.amazonaws.com", true},
		{"ideas-are-more-powerful-than-guns", true},
		{"testbucket", true},
		{"1bucket", true},
		{"bucket1", true},

    assertFalse(delegates.get(0).cancel(true));
    // Cancel the delegate before the input future is done
    assertTrue(delegates.get(1).cancel(true));
    // Setting the future still works since cancellation didn't propagate
    assertTrue(future2.set(2L));
    // Second check to ensure the input future was not cancelled
    assertEquals((Long) 2L, getDone(future2));

    assertFalse(delegates.get(0).cancel(true));
    // Cancel the delegate before the input future is done
    assertTrue(delegates.get(1).cancel(true));
    // Setting the future still works since cancellation didn't propagate
    assertTrue(future2.set(2L));
    // Second check to ensure the input future was not cancelled
    assertEquals((Long) 2L, getDone(future2));

### Comprendre le fonctionnement de l'import { #how-the-importing-works }

La section :

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

signifie :

* En partant du même package dans lequel vit ce module (le fichier `app/main.py`) (le répertoire `app/`)...

### Cómo funciona la importación { #how-the-importing-works }

La sección:

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

significa:

* Partiendo en el mismo paquete en el que este módulo (el archivo `app/main.py`) habita (el directorio `app/`)...

### Como funciona a importação { #how-the-importing-works }

A seção:

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

significa:

* Começando no mesmo pacote em que este módulo (o arquivo `app/main.py`) vive (o diretório `app/`)...

Оскільки файли `app/routers/users.py` та `app/routers/items.py` - це підмодулі, що є частиною того самого пакета Python `app`, ми можемо використати одну крапку `.` для «відносних імпортів».

### Як працює імпорт { #how-the-importing-works }

Розділ:

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

означає:

* Починаючи в тому самому пакеті, де знаходиться цей модуль (файл `app/main.py`) (каталог `app/`)...

`app/routers/users.py`와 `app/routers/items.py` 파일은 같은 Python package `app`에 속한 submodule들이므로, 점 하나 `.`를 사용해 "상대 import"로 가져올 수 있습니다.

### import가 동작하는 방식 { #how-the-importing-works }

다음 구문은:

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

의미는 다음과 같습니다:

* 이 모듈(파일 `app/main.py`)이 속한 같은 package(디렉터리 `app/`)에서 시작해서...
* subpackage `routers`(디렉터리 `app/routers/`)를 찾고...
