변수 `item`은 `items`의 개별 요소라는 사실을 알아두세요.

그리고 에디터는 계속 `str`라는 사실을 알고 도와줍니다.

#### `Tuple`과 `Set`

`tuple`과 `set`도 동일하게 선언할 수 있습니다.

{* ../../docs_src/python_types/tutorial007.py hl[1,4] *}


이 뜻은 아래와 같습니다:

* 변수 `items_t`는, 차례대로 `int`, `int`, `str`인 `tuple`이다.
* 변수 `items_s`는, 각 아이템이 `bytes`인 `set`이다.

#### `Dict`

`dict`를 선언하려면 컴마로 구분된 2개의 파라미터가 필요합니다.

첫 번째 매개변수는 `dict`의 키(key)이고,

	// trying to pool FS backend into an Erasure set.
	if err = checkFormatErasureValues(formatConfigs, storageDisks, setDriveCount); err != nil {
		return nil, err
	}

	// All disks report unformatted we should initialized everyone.
	if shouldInitErasureDisks(sErrs) && firstDisk {
		logger.Info("Formatting %s pool, %v set(s), %v drives per set.",
			humanize.Ordinal(poolCount), setCount, setDriveCount)

      }

      // don't try to remove the set if it's empty; that can't be done safely without a lock
      // anyway, if the set is empty it'll just be wrapping an array of length 0
    }
  }
