The Python manual's claim there is solidly grounded. The logic
of 'types' is reasonably well-defined in the discipline. Each
instance of a type takes exactly one element from the type's
set of values (at least at a particular time).

Whether the '==' operation conforms to your idea of what equality
means is unclear. Maybe I was wrong, and the object's identity
is part of its abstract state.

We know that's not true.
