有什么方法可以在属性中使用方法吗？

class MyClass:
    def __init__(self):
        self._value = 0

    @property
    def value(self):
        return self._value

    @value.setter
    def value(self, new_value):
        self._value = new_value

    @property
    def doubled_value(self):
        return self._value * 2

my_obj = MyClass()
my_obj.value = 5
print(my_obj.value)  # 输出：5
print(my_obj.doubled_value)  # 输出：10

def double_property(prop):
    @property
    def getter(self):
        return prop.fget(self) * 2

    @prop.setter
    def setter(self, value):
        prop.fset(self, value * 2)

    return property(getter, setter)

class MyClass:
    @double_property
    def value(self):
        return self._value

    @value.setter
    def value(self, new_value):
        self._value = new_value

my_obj = MyClass()
my_obj.value = 5
print(my_obj.value)  # 输出：10
