Python类访问限制

如果要让内部属性不被外部访问，可以把属性的名称前加上两个下划线__，在Python中，实例的变量名如果以__开头，就变成了一个私有变量（private），只有内部可以访问，外部不能访问

class Student(object):

    def __init__(self, name, score):
        self.__name = name
        self.__score = score

    def print_score(self):
        print('%s: %s' % (self.__name, self.__score))
        
bart = Student('Bart Simpson', 59)
bart.__name

AttributeError: 'Student' object has no attribute '__name'

    
class Student(object):

    def __init__(self, name, score):
        self.__name = name
        self.__score = score

    def print_score(self):
        print('%s: %s' % (self.__name, self.__score))
    def get_name(self):
        return self.__name
    
bart = Student('Bart Simpson', 59)

print(bart.get_name())

Bart Simpson
