Since there is a valid use-case for class-private members (namely to avoid name clashes of names with names defined by subclasses), there is limited support for such a mechanism, calledname mangling.Any identifier of the form__spam(at least two leading underscores, at most one trailing under...

non-public instance variables (非公共实例变量),在变量名前使用下划线(_)。 “除了从对象内部外无法被访问的‘Private’实例变量在Python中并不存在。然而,这里有一个多数Python代码都会遵守的惯例:使用下划线作为前缀的命名(例如 _spam)应该被认为是API的非公开部分(不管是函数、方法还是数据成员)” — Pytho...
