使用@property和@x.setter装饰器

class Student:    def __init__(self, name, gender):        self.name = name        self.__gender = gender    @property    def gender(self):        return self.__gender    @gender.setter    def gender(self, value):
        # 此处为对参数做检查的逻辑        self.__gender = valuebart = Student('Bart', 'male')print(bart.gender)bart.gender = 'female'
