I am not sure what you mean by 'wrapped'. Your subject line says
something different. In any case, is your universe *all* Python objects
or some subset?

Builtin classes, named or not, do not have dotted names

>>> 1 .__class__
<class 'int'>
>>> class C: pass

I believe all others do, including C-coded extension classes.

>>> C().__class__
<class '__main__.C'>
