Python typing.get_origin用法及代码示例用法: typing.get_origin(tp) 为泛型类型和特殊类型形式提供基本的自省。 对于X[Y, Z, ...] 形式的输入对象,这些函数返回 X 和(Y, Z, ...) 。如果X 是内置类或collections 类的通用别名,它会被规范化为原始类。如果 X 是一个联合或 Literal 包含在另一个泛型...
For unsupported objects return None and () correspondingly. Examples: assert get_origin(Dict[str, int]) is dict assert get_args(Dict[int, str]) == (int, str) assert get_origin(Union[int, str]) is Union assert get_args(Union[int, str]) == (int, str) 3.8 新版功能....
typing.get_origin(tp) typing.get_args(tp) Provide basic introspection for generic types and special typing forms. For a typing object of the form X[Y, Z, ...] these functions return X and (Y, Z, ...). If X is a generic alias for a builtin or collections class, it gets ...
typing.get_origin(type(TestModel).__fields__['tags'].type_) is List typing.get_origin(type(TestModel).__fields__['tags'].type_) == List 令人沮丧的是,这确实返回True: type(TestModel).__fields__['tags'].type_ is str 我确认字段是List类型的正确方法是什么?

importtyping_inspectprint(typing_inspect.get_origin(typing.List[int])) 1. 2. 3. 该代码会输出<class 'list'>,表示我们已成功导入typing_inspect库,并且能够获取到typing.List的原始类型。 至此,我们已经完成了typing_inspect库的安装和验证。 总结
