如何让一个类充当两个元素元组和解包元素？

class MyClass:
    def __init__(self, element1, element2):
        self.element1 = element1
        self.element2 = element2

    def __iter__(self):
        return self

    def __next__(self):
        if hasattr(self, 'element1') and hasattr(self, 'element2'):
            element1 = self.element1
            element2 = self.element2
            del self.element1
            del self.element2
            return element1, element2
        else:
            raise StopIteration

# 创建一个实例对象
my_obj = MyClass('Hello', 'World')

# 解包元素
element1, element2 = next(my_obj)

print(element1)  # 输出：Hello
print(element2)  # 输出：World
