Here is a branch with this proposed change:

             sage: from sage.geometry.polyhedron.palp_database import Reflexive4dHodge
             sage: Reflexive4dHodge(1,101)  # optional - polytopes_db_4d
-            <class 'sage.geometry.polyhedron.palp_database.Reflexive4dHodge'>
+            <sage.geometry.polyhedron.palp_database.Reflexive4dHodge object at ...>
         """
         dim = 4
         if data_basename is None:

Did that change between Python 2 and Python 3?

Or among Python 3.y.z versions, can it can depend on y?
