With Foo and Bar like the OP coded (just two new style classes, f is instance of Foo), see this: >>> f <__main__.Foo object at 0xb7d1280c> >>> setattr(f, '__class__', Bar) >>> f <__main__.Foo object at 0xb7d1280c> Ok, didn't work, try your way: >>> object.__setattr__(f, '__class__', Bar) >>> f <__main__.Bar object at 0xb7d1280c> Wow! Ok, but getting back to Foo, with the *former* method: >>> setattr(f, '__class__', Foo) >>> f <__main__.Foo object at 0xb7d1280c> I can't explain this to myself, :( Regards, -- . Facundo .
