Це означає:

* Змінна `prices` це `dict`:
    * Ключі цього `dict` типу `str` (наприклад, назва кожного елементу).
    * Значення цього `dict` типу `float` (наприклад, ціна кожного елементу).

#### Union (об'єднання)

#### 字典

定义 `dict` 时，需要传入两个子类型，用逗号进行分隔。

第一个子类型声明 `dict` 的所有键。

第二个子类型声明 `dict` 的所有值：

{* ../../docs_src/python_types/tutorial008.py hl[1,4] *}


这表示：

* 变量 `prices` 是一个 `dict`：
    * 这个 `dict` 的所有键为 `str` 类型（可以看作是字典内每个元素的名称）。
    * 这个 `dict` 的所有值为 `float` 类型（可以看作是字典内每个元素的价格）。

### 类作为类型

你也可以将类声明为变量的类型。

假设你有一个名为 `Person` 的类，拥有 name 属性：

	var wg sync.WaitGroup
	wg.Add(1)
	var listErr error

	go func(o listPathOptions) {
		defer wg.Done()
		if o.Lifecycle == nil {
			// No filtering ahead, ask drives to stop
			// listing exactly at a specific limit.
			o.StopDiskAtLimit = true
		}
		listErr = z.listMerged(listCtx, o, filterCh)
		o.debugln("listMerged returned with", listErr)
	}(*o)
