Could you expand on that? I’m not sure what exactly you’re saying, because you’re not using standard or unambiguous terminology. (`type` is a thing, but “class” isn’t a thing, but rather a category of things, a syntactic construct.)

Python 2:

  >>> class OldStyleClass: pass
  >>> isinstance(OldStyleClass, type)
  False

  >>> class NewStyleClass(object): pass
  >>> isinstance(NewStyleClass, type)
  True

Python 3:

  >>> class Class: pass
  >>> isinstance(Class, type)
  True

Old-style classes were kind of their own thing in their own space, but with new-style classes, classes are to `type` as instances are to `object`, and I don’t recall there being any major 2/3 difference beyond the simple removal of old-style classes.
