领域知识

Python 3.10+用内置类型（liststr], dictstr, int], str | None），低版本用typing模块
OptionalX]等价于X | None，表示可能为None，不表示"可选参数"
函数签名：所有公开函数标注参数类型和返回类型，内部函数可省略
泛型：TypeVar定义类型变量，GenericT]创建泛型类，bound限制上界
Protocol：结构化子类型（鸭子类型的静态版），定义接口不需要继承
TypedDict：字典的精确类型，每个key有独立类型，total=False允许可选key
Literal：限制值为几个字面量之一，如Literal"read", "write"]
Callable参数类型], 返回类型]标注回调函数，参数多时用Protocol替代
overload装饰器：同一函数不同参数组合返回不同类型时使用
TYPE_CHECKING：避免运行时循环导入，仅在类型检查时导入
