I want to get a class type parameter, but I don't know how to do it. I've looked everywhere, but I haven't found an answer. Here's the code with the imaginary method get_attr I'm waiting for if it exists:
class test:
def get_attr(self):
pass
obj: test[int] = test()
obj.get_attr()
#return int
obj2: test[str, list] = test()
obj2.get_attr()
#return (str, list)
是否存在这样的功能或方法？如果没有，我可以创建它吗？ （顺便说一下，我不知道它是否在python xD中被命名为“类类型参数”，我已经在Java和在线研究中看到了它。）
