Briefly understand python private and public attributes

In python, variables outside methods within a class are called attributes, and variables within methods within a class are called fields. Their private and public access methods are similar.

class C:
    __name="私有属性"

    def func(self):
        print(C.__name)

class sub_C(C):
    def info(self):
        print(C.__name)#派生类中不可以访问父类的私有字段
obj=C()
obj.func()
obj=sub_C()
obj.info()

The access to methods and properties is similar to the above method, that is: private members can only be used inside the class
