为什么 python 没有像 c#、java 中那样的访问修饰符，即 public、private 等。在 python 中封装和信息隐藏的替代方法是什么。

Answer 1

来自 Wikipedia :

[Python] has limited support for private variables using name mangling. See the "Classes" section of the tutorial for details. ManyPython users don't feel the need for private variables, though. Theslogan "We're all consenting adults here" is used to describe thisattitude. Some consider information hiding to be unpythonic, inthat it suggests that the class in question contains unaesthetic orill-planned internals. However, the strongest argument for namemangling is prevention of unpredictable breakage of programs:introducing a new public variable in a superclass can break subclassesif they don't use "private" variables.

From the tutorial:As is truefor modules, classes in Python do not put an absolute barrier betweendefinition and user, but rather rely on the politeness of the user notto "break into the definition."
