静态属性

 1 class Room:
 2     def __init__(self, name, owner, width, length, heigh):
 3         self.name = name
 4         self.owner = owner
 5         self.width = width
 6         self.length = length
 7         self.heigh = heigh
 8 
 9     @property  # 函数属性变为数据属性，调用方式改变
10     def cal_area(self):
11         # print('%s 住的 %s 总面积是%s' % (self.owner, self.name, self.width * self.length))
12         return self.width * self.length
13 
14     @property
15     def cal_total(self):
16         return self.width * self.length * self.height

19 r1 = Room('厕所', 'alex', 100, 100, 100000)
20 r2 = Room('公共厕所', '袁浩', 10, 1, 10)
21 print('%s 住的 %s 总面积是%s' % (r1.owner, r1.name, r1.width * r1.length))
22 r1.cal_area()
23 r2.cal_area()
24 print(r1.cal_area)
25 print(r2.cal_area)
26 print(Room.cal_area)
27 print(r1.cal_total)
28 输出：
29 1000000000
调用函数属性可以变为像调用数据属性叫静态属性
