使用@property时报错maximum recursion depth exceeded

class Stu(object):
    @property
    def score(self):
        return self.score  # 用property 最好._

    @score.setter
    def score(self,value):
        if not isinstance(value,int):
            raise ValueError("分数必须是整数")
        if value < 0 or value >100:
            raise ValueError("分数必须在0-100之间")

        self.score = value



ss = Stu()

ss.score = 70
print(ss.score)

# 报错 RecursionError: maximum recursion depth exceeded

　　

这主要时是使用@property封装属性时 需要将属性设置成._即可,如下

class Stu(object):
    @property
    def score(self):
        return self._score

    @score.setter
    def score(self,value):
        if not isinstance(value,int):
            raise ValueError("分数必须是整数")
        if value < 0 or value >100:
            raise ValueError("分数必须在0-100之间")

        self._score = value



student = Stu()

student.score = 65
print(student.score)
