python-静态属性,,@property的
@property的作用是:直接运行被装饰的函数,不能带参数,表面上看就是在被装饰的函数后面直接加括号。
class Room: tag=1 def __init__(self,name,owner,width,length,heigh): self.name=name self.owner=owner self.width=width self.length=length self.heigh=heigh @property def cal_area(self): # print(‘%s 住的 %s 总面积是%s‘ % (self.owner,self.name, self.width * self.length)) return self.width * self.length @classmethod def tell_info(cls,x): print(cls) print(‘--》‘,cls.tag,x)#print(‘--》‘,Room.tag) # def tell_info(self): # print(‘---->‘,self.tag) @staticmethod def wash_body(a,b,c): print(‘%s %s %s正在洗澡‘ %(a,b,c)) def test(x,y): print(x,y)# Room.wash_body(‘张三‘,‘李四‘,‘王五‘)print(Room.__dict__)r1=Room(‘卧室‘,‘张三‘,100,100,100000)print(r1.__dict__)# r1.wash_body(‘张三‘,‘李四‘,‘王五‘)# Room.test(1,2)# r1.test(1,2)
