注意，变量 `item` 是列表 `items` 中的元素之一。

而且，编辑器仍然知道它是一个 `str`，并为此提供了支持。

#### 元组和集合

声明 `tuple` 和 `set` 的方法也是一样的：

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


这表示：

* 变量 `items_t` 是一个 `tuple`，其中的前两个元素都是 `int` 类型, 最后一个元素是 `str` 类型。
* 变量 `items_s` 是一个 `set`，其中的每个元素都是 `bytes` 类型。

#### 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。

*----+------+------+
| <<<*>>> | user properties, set from CLI with <<<-Dproperty=value>>> | <<<$\{skipTests\}>>> |
*----+------+------+
| <<<*>>> | model properties, such as project properties set in the pom | <<<$\{any.key\}>>> |
*----+------+------+
| <<<maven.home>>> | The path to the current Maven home. | <<<$\{maven.home\}>>> |

/// tip | Consejo

La sintaxis `{"name", "description"}` crea un `set` con esos dos valores.

Es equivalente a `set(["name", "description"])`.

#### Usar `list`s en lugar de `set`s { #using-lists-instead-of-sets }

Si olvidas usar un `set` y usas un `list` o `tuple` en su lugar, FastAPI todavía lo convertirá a un `set` y funcionará correctamente:
