typing.get_type_hints()可以做的范围似乎是有限制的。我觉得这很奇怪,这种类型构造在其他场景中似乎不是问题。一些快速测试发现,作为另一个类类型的子类,它可以很好地处理您的Test类型。以前就了解过Java泛型的实现是不完整的,最近在做一些代码重构的时候遇到一些Java泛型类型擦除的问题,简单的来说,Java泛型中所
用法: typing.get_type_hints(obj, globalns=None, localns=None, include_extras=False) 返回包含函数、方法、模块或类对象的类型提示的字典。 这通常与obj.__annotations__相同。此外,编码为字符串文字的前向引用是通过在globals和locals命名空间中评估它们来处理的。如有必要,如果设置了等于None的默认值,则会为...

Type hints in Python involve a colon and a type declaration after the first invocation of a name in a namespace. Here’s an example: name:strage:intname =input("Your name?") age =int(input("Your age?"))# alternatively, and more simply:name:str=input("Your name?") age:int=int(in...

I'm not sure if you're aiming for exact compatibility among python versions for all of the functions you support or not. But due to python/cpython#90353, get_type_hints with include_extras=True has inconsistent behavior among python vers...
