Python class inherits object

Question

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

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

Answer 1

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

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.
