快速設定self.arg=arg？

[anniehuang921]

有沒有更快的？ 本來是這樣：

class loto(self):
       def __init__(self,x,y,z):
              self.x=x
              self.y=y
              self.z=z

快速設定self.arg=arg?

Good Question!

限制三個變數，並且用a=A(1,2,3)取代a=A(x=1,y=2,z=3)

class A(object):
    def __init__(self,*args):
        assert len(args) <= 3
        args_names = ["x","y","z"]
        kwargs = dict(zip(args_names[:len(args)],args))
        self.__dict__.update(kwargs)

ps.“一”到三個變數都可以呦～～
