Python @property setter可以設置多個屬性值嗎

請教大神，Python @property setter可以設置多個屬性值嗎？
例如
class A():
...
@property
def a(self,x,y): ...
@a.setter
def a(self,x,y): self.x=x; self.y=y

最佳回答：

你可以傳tuple，list等

 class A(object):
    def __init__(self, val):
        self.idx = val

    @property    
    def idx(self):
        return self._idx

    @idx.setter
    def idx(self, val):
        try:
            value1, value2 = val
        except ValueError:
            raise ValueError("Pass an iterable with two items")
        else:
            """ This will run only if no exception was raised """
            self._idx = sha512(value1+value2)

Demo

 >>> a = A(['foo', 'bar'])     #pass a list
>>> b = A(('spam', 'eggs'))   #pass a tuple
>>> a.idx
<sha512 HASH object @ 0xa57e688>
>>> a.idx = ('python', 'org')  #works
>>> b.idx = ('python',)         #fails
Traceback (most recent call last):
    ...
    raise ValueError("Pass an iterable with two items")
ValueError: Pass an iterable with two items
