如何在父类方法中克隆子类实例

class ParentClass:
    def clone(self):
        return self.__class__()

class ChildClass(ParentClass):
    def __init__(self):
        self.attribute = "example"

    def clone(self):
        cloned_instance = super().clone()  # 调用父类的克隆方法，获取克隆的基础实例
        cloned_instance.attribute = self.attribute  # 克隆子类特有的属性
        return cloned_instance

# 创建子类实例
child = ChildClass()

# 克隆子类实例
clone_child = child.clone()

# 验证克隆是否成功
print(isinstance(clone_child, ChildClass))  # 输出：True
print(clone_child.attribute)  # 输出：example
