1. 要解決的問題： 想要快速的通路類中的私有屬性，但是不想直接暴露出原來類中的屬性
@property
def tick(self):
return self._tick
2. 經典例子
# property decorator make defining and modifying class's property easy
class Student:
@property
def score(self):
return self.__score
@score.setter
def score(self, score):
if isinstance(score, int):
self.__score = score
else:
raise TypeError('score must be int')
if __name__ == '__main__':
s = Student()
s.score = 'jjj'
print(s.score)
3. 直接使用類的方法名字， 而不是直接使用類的屬性
class Student:
def __init__(self, score):
self.__score = score
def set_score(self, set_score):
self.__score = set_score
@property
def return_score(self):
return self.__score
if __name__ == '__main__':
s = Student(4)
print(s.return_score)
s.set_score(44)
print(s.return_score)
