关于property

Question

class Rectangle:

def __init__(self):
    self.width = 0
    self.height = 0
def setSize(self, size):
    self.width, self.height = size
def getSize(self):
    return self.width, self.height
@property
def size(self):
    return (self.width,self.height)
    
    

a=Rectangle()

我想问下,怎么才能实现

a.size=(width,height)
就是说设置size为a的一个property.
我用了装饰器,但打印a.size直接返回的是property object.而不是我要的那个值.
如果不考虑用size=property(getSize,setSize)
需要重写代码吗?先谢了.

class Rectangle(object):

    def __init__(self):
        self.width = 0
        self.height = 0

    @property
    def size(self):
        return (self.width, self.height)

    @size.setter
    def size(self, size):
        self.width, self.height = size

a = Rectangle()
print a.size    #(0, 0)

a.size = (3, 4)
print a.size    #(3, 4)

是不是这样？
