@property@XXX.setter
br/>@XXX.setter<br/设置一个可读写属性
仅使用@property，设置一个只读属性
class Student(object):
@property
def score(self):
return self._score
@score.setter
def score(self, value):
if not isinstance(value, int):
raise ValueError('score must be an integer!')
if value < 0 or value > 100:
raise ValueError('score must between 0 ~ 100!')
self._score = value使用@property后，调用函数变为函数名称的属性赋值、读取
s.score = 60 # OK，实际转化为s.set_score(60)
s.score # OK，实际转化为s.get_score()
