## Importez le `BaseModel` de Pydantic

Commencez par importer la classe `BaseModel` du module `pydantic` :

{* ../../docs_src/body/tutorial001.py hl[4] *}

```

////

//// tab | Python 3.9 і вище

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial008_py39.py!}
```

////

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：

```Python hl_lines="1  4"
{!../../docs_src/python_types/tutorial008.py!}
```

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：

 * due to eviction resulting from timed expiration, exceeding a maximum size, or garbage collection.
 *
 * <p>An instance may be called concurrently by multiple threads to process different entries.
 * Implementations of this interface should avoid performing blocking calls or synchronizing on
 * shared resources.
