python的静态，组态，继承3-静态方法

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  # 跟实例绑定
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  # 类的装饰器
def tell_info(cls, x):
    print(cls)
    print('--》', cls.tag, x)  # print('--》',Room.tag)

# def tell_info(self):
#     print('---->',self.tag)

@staticmethod  # 类的工具包
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(‘alex’, ‘lzp’, ‘yxm’)

r1 = Room(‘厕所’, ‘alex’, 100, 100, 100000) # 实例化
r1.wash_body(‘alex’, ‘lzp’, ‘yxm’)

Room.test(1, 2)

r1.test(1,2)#不能使用，r1会把自己传进去与1,2冲突

实例化只有数据属性，没有函数属性

静态方法只是类的工具包

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  # 跟实例绑定
    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  # 类的装饰器
    def tell_info(cls, x):
        print(cls)
        print('--》', cls.tag, x)  # print('--》',Room.tag)

    # def tell_info(self):
    #     print('---->',self.tag)

    @staticmethod  # 类的工具包
    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('alex', 'lzp', 'yxm')

r1 = Room('厕所', 'alex', 100, 100, 100000)  # 实例化
r1.wash_body('alex', 'lzp', 'yxm')

Room.test(1, 2)
# r1.test(1,2)#不能使用，r1会把自己传进去与1,2冲突
