python - 类的修饰符

Posted 2020-07-30

一、私有：

只能类自己本身成员内部可以访问

class Foo:
    def __init__(self,name):
        self.__name = name  #私有的
    def f1(self):
        print(self.__name)


obj = Foo(‘alex‘)
#print(obj.__name)  #不能这样访问
obj.f1()

out:

alex

class Foo:
    __cc = "123"
    def __init__(self,name):
        self.__name = name
    def f1(self):
        print(self.__name)
    @staticmethod
    def f3():
        print(Foo.__cc)



Foo.f3()

out:

123

二、公有:
