如何动态修改类的魔法方法？

  我希望用python做个指针类，它可以被多重继承，然后拥有多重继承的第二个类的方法和代码提示，但它好像并不能调用被指向对象的魔法方法  我不希望在Pointer类里面重写所有魔法方法，不仅是因为麻烦，更是因为这样没有代码提示了

环境：windows11 x64python3.9

• Pointer.py

  class Pointer:
  
    def __new__(cls, *args, **kwargs):
        if cls == Pointer:
            return super().__new__(cls)
        if 'cls_' in kwargs:
            kwargs.pop('cls_')
        return Pointer(*args, **kwargs, cls_=cls)
  
    def __init__(self, value=None, *, cls_=None):
        self.__interior = True
        self.__value = value
        for i in dir(value):
            if i != '__class__':
                if i in cls_.__dict__:
                    # print(i)
                    setattr(self, i, cls_.__dict__[i])
                try:
                    setattr(self, i, getattr(value, i))
                except AttributeError:
                    pass
        self.__interior = False
  
  
  class StrPointer(Pointer, str):
    pass

• test.py

  from Pointer import StrPointer
  
  
  s = StrPointer('a')
  print(s.__str__())
  print(s)

• 输出

  a
