Typehint

ASecurity

- Python 3.10+用内置类型(list[str], dict[str, int], str | None),低版本用typing模块 - Optional[X]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,Generic[T]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
