#### Случайный элемент { #a-random-item }

С помощью `data.items()` мы получаем <dfn title="Объект, по которому можно итерироваться циклом for, например список, множество и т.п.">итерируемый объект</dfn> с кортежами, содержащими ключ и значение для каждого элемента словаря.

Мы превращаем этот итерируемый объект в обычный `list` через `list(data.items())`.

### typing 模块 { #typing-module }

在一些额外的用例中，你可能需要从标准库的 `typing` 模块导入内容。比如当你想声明“任意类型”时，可以使用 `typing` 中的 `Any`：

```python
from typing import Any


def some_function(data: Any):
    print(data)
```

### 泛型类型 { #generic-types }

有些类型可以在方括号中接收“类型参数”（type parameters），用于声明其内部值的类型。比如“字符串列表”可以写为 `list[str]`。

这些能接收类型参数的类型称为“泛型类型”（Generic types）或“泛型”（Generics）。

In your WebSocket route you can `await` for messages and send messages.

{* ../../docs_src/websockets_/tutorial001_py310.py hl[48:52] *}

You can receive and send binary, text, and JSON data.

## Try it { #try-it }

Put your code in a file `main.py` and then run your application:
