It defines certain primitives, like strings and integers.  But it doesn't define what an OBJECT is.  So you and everyone else are beating around the bush trying to define something that the LANGUAGE ITSELF doesn't define.  So, don't make a claim about it.

I'm not saying this for dreamingforward's benefit, as he clearly isn't
interested in learning, but in case the OP is confused: Checking the
type of something doesn't tell you what it isn't. The isinstance check
is true, because type is an instance of type, which is a subclass of
object, therefore type is an instance of object. Similarly, you could
check this:

>>> issubclass(type, object)
True

So you can see that a type IS an object.
