Python类继承对象 [英] Python class inherits object

问题描述

是否有任何理由让类声明继承自 object ？

Is there any reason for a class declaration to inherit from object?

我刚刚找到一些代码这是我找不到一个很好的理由为什么。

I just found some code that does this and I can't find a good reason why.

class MyClass(object):
    # class code follows...

推荐答案

风格对象。这是在python2.2中引入的一个特性。

Yes, this is a 'new style' object. It was a feature introduced in python2.2.

新风格对象具有与经典对象不同的对象模型，有些东西不能与旧风格对象正常工作，例如，super（），@property和描述符。请参阅这篇文章，了解新风格类的详细说明：

New style objects have a different object model to classic objects, and some things won't work properly with old style objects, for instance, super(), @property and descriptors. See this article for a good description of what a new style class is:
