You probably don't want to be using __new__ here. Try using __init__ instead, or simply not defining __new__ at all. I suspect that the reason that appears to work under Py2 is that you're using an old-style class, there. That means it'll be subtly different on the two versions. To make them do the same thing, explicitly subclass object: class LPU1(object): In Python 3, that's redundant - subclassing object is the default. In Python 2, though, it's important.
