Python setattr()也__setattr__有什么区别联系呢？看了个 stackoverflow 答案，不是太懂，各位求解释下。

setattr(obj, attr, value) just calls obj.setattr(attr, value), at least for new-style classes.

setattr(instance, name, value) is syntactic sugar for instance.setattr(name, value).

You would only need to call object.setattr(...) inside a class definition, and then only if directly subclassing object -- if you were subclassing something else, Spam for example, then you should either use super() to get the next item in the heirarchy, or call Spam.setattr(...) -- this way you don't risk missing behavior that super-classes have defined by skipping over them directly to object.

The code is probably using object.setattr for the exact purpose of skipping the superclass's setattr

英文好的麻烦给翻译翻译上面的 4 段话的意思。感谢！
