# NoneBot.typing 模块
|

|
|
||
|
## 类型
|
||
|
|
||
|
下面的文档中,「类型」部分使用 Python 的 Type Hint 语法,见 [PEP 484](https://www.python.org/dev/peps/pep-0484/)、[PEP 526](https://www.python.org/dev/peps/pep-0526/) 和 [typing](https://docs.python.org/3/library/typing.html)。
|
||
|
|
||
|
除了 Python 内置的类型,下面还出现了如下 NoneBot 自定类型,实际上它们是 Python 内置类型的别名。
