静态属性

class Room:
    def __init__(self, name, owner, width, length, heigh):
        self.name = name
        self.owner = owner
        self.width = width
        self.length = length
        self.heigh = heigh

    @property  # 函数属性变为数据属性，调用方式改变
    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

    @property
    def cal_total(self):
        return self.width * self.length * self.height


r1 = Room('厕所', 'alex', 100, 100, 100000)
r2 = Room('公共厕所', '袁浩', 10, 1, 10)
print('%s 住的 %s 总面积是%s' % (r1.owner, r1.name, r1.width * r1.length))
r1.cal_area()
r2.cal_area()
print(r1.cal_area)
print(r2.cal_area)
print(Room.cal_area)
print(r1.cal_total)
输出：
1000000000

调用函数属性可以变为像调用数据属性    叫静态属性
