改变类的私有变量的值有2种方法:
间接:为这个私有变量提供一个操作的方法,如:def get_score(self, score)
直接:实例名._类名__私有变量名 = 值, 如:f._Student__score = 10
间接
#!/usr/bin/python # -*- coding: utf-8 -*- class Student(object): def __init__(self,name, score): self.__name = name self.__score = score def set_score(self, score): if score < 11: print "false" return False self.__score = score return self.__score def get_score(self): return self.__score f = Student('hah', 11) print f.get_score() f.set_score(12) print f.get_score()
运行结果:
11 12
2.直接
#!/usr/bin/python # -*- coding: utf-8 -*- class Student(object): def __init__(self,name, score): self.__name = name self.__score = score def set_score(self, score): if score < 11: print "false" return False self.__score = score return self.__score def get_score(self): return self.__score f._Student__score=13 print f.get_score()
运行结果:
13
