python中private、protected&public private: 1.在类中的属性或者方法前加上两条下划线“__”,该属性或方法就变成了私有的了,只能在类内访问。 2.如果想从外部访问私有属性或者方法(不建议访问),有两种方法,一是定义一个函数进行访问,二是对私有的属性或者方法的名字进行转换为:一个下划线“_”+类名+私有属性或...
1. python中没有private、protected,但是有个惯例 官方文档是这么写的: 9.6. Private Variables and Class-local References “Private” instance variables that cannot be accessed except from inside an object don’t exist in Python. However, there is a convention that is followed by most Python code: ...
that will do the job (public, protected and private). But there’s no such a thing in Python. That might be a little confusing at first, but it’s possible too. We’ll have look at how do itrightin Python.
