[Python]@property的使用

Posted on

Why @property?

如果对于一个类，我们希望用getter和setter来控制成员变量的赋值和取值，又不希望对于每一个成员变量都显式的写出getter和setter， 就可以用@property

class Student:
    
    # this is the getter
    @property
    def score(self):
        return self._score
    
    # this is the setter
    @score.setter
    def score(self, value):
        # value check here
        self._score = value

When calling

Student().score # get_score
# instead of Student()._score directly
