### Прості типи

Ви можете оголошувати усі стандартні типи у Python, не тільки `str`.

Ви можете використовувати, наприклад:

* `int`
* `float`
* `bool`
* `bytes`

```Python hl_lines="1"
{!../../docs_src/python_types/tutorial005.py!}
```

### Generic-типи з параметрами типів

```

## 声明类型

你刚刚看到的就是声明类型提示的主要场景。用于函数的参数。

这也是你将在 **FastAPI** 中使用它们的主要场景。

### 简单类型

不只是 `str`，你能够声明所有的标准 Python 类型。

比如以下类型：

* `int`
* `float`
* `bool`
* `bytes`

```Python hl_lines="1"
{!../../docs_src/python_types/tutorial005.py!}
```

### 嵌套类型

有些容器数据结构可以包含其他的值，比如 `dict`、`list`、`set` 和 `tuple`。它们内部的值也会拥有自己的类型。

你可以使用 Python 的 `typing` 标准库来声明这些类型以及子类型。
