如何在传递接口时访问不同具体类的属性

from abc import ABC, abstractmethod

class IMyInterface(ABC):
    @property
    @abstractmethod
    def my_attribute(self):
        pass

class ConcreteClass(IMyInterface):
    def __init__(self, value):
        self._my_attribute = value

    @property
    def my_attribute(self):
        return self._my_attribute

def use_interface(obj: IMyInterface):
    print(obj.my_attribute)

# 使用示例
obj = ConcreteClass("Hello, World!")
use_interface(obj)

def safe_use_interface(obj: IMyInterface):
    try:
        print(obj.my_attribute)
    except AttributeError as e:
        print(f"Error: {e}")

# 模拟一个不正确的对象
class IncorrectClass:
    pass

incorrect_obj = IncorrectClass()
safe_use_interface(incorrect_obj)  # 输出: Error: can't set attribute
