class Screen(object):
    @property
    def width(self):
        return self._width
    @width.setter
    def width(self,value):
        self._width=value
    @property
    def height(self):
        return self._height
    @height.setter
    def height(self,value):
        self._height=value
    @property
    def resolution(self):
        return self._height*self._width

s = Screen()
s.width = 1024
s.height = 768
print (s.resolution)
assert s.resolution == 786432, '1024 * 768 = %d ?' % s.resolution

结果： 78336

assert的用法：如果没有得到786432这个值，会输入AssertionError: 1024 * 768 = 78336 ?

Traceback (most recent call last): File "C:/Users/air/AppData/Local/Programs/Python/Python35/ScreenProperty.py", line 22, in <module> assert s.resolution == 786432, '1024 768 = %d ?' % s.resolution AssertionError: 1024 768 = 78336 ?
