有没有办法在另一个类中改变类初始化中的self变量？

class MyClass:
    def __init__(self, value):
        self.value = value

    def modify_self(self, new_value):
        self.value = new_value

class AnotherClass:
    def __init__(self):
        self.my_instance = MyClass(10)

    def modify_my_instance(self, new_value):
        self.my_instance.modify_self(new_value)

another_instance = AnotherClass()
print(another_instance.my_instance.value)  # 输出：10

another_instance.modify_my_instance(20)
print(another_instance.my_instance.value)  # 输出：20
