class Screen(object): @property def width(self): return self._width

@width.setter
def width(self,w):
    self._width=w

@property
def height(self):
    return self._height

@height.setter
def height(self,h):
    self._height=h

@property
def resolution(self):
    return self._width*self._height

测试:

s = Screen() s.width = 1024 s.height = 768 print('resolution =', s.resolution) if s.resolution == 786432: print('测试通过!') else: print('测试失败!')
