没有类型的话，这几乎是不可能做到的。

注意，变量 `item` 是列表 `items` 中的一个元素。

即便如此，编辑器仍然知道它是 `str`，并为此提供支持。

#### 元组和集合 { #tuple-and-set }

声明 `tuple` 和 `set` 的方式类似：

{* ../../docs_src/python_types/tutorial007_py310.py hl[1] *}

这表示：

* 变量 `items_t` 是一个含有 3 个元素的 `tuple`，分别是一个 `int`、另一个 `int`，以及一个 `str`。
* 变量 `items_s` 是一个 `set`，其中每个元素的类型是 `bytes`。

#### 字典 { #dict }

定义 `dict` 时，需要传入 2 个类型参数，用逗号分隔。

第一个类型参数用于字典的键。

You can set the OpenAPI `operationId` to be used in your *path operation* with the parameter `operation_id`.

You would have to make sure that it is unique for each operation.
