'Value' and 'object' are indeed synonymous as long as you keep in mind
that:
>>> -12 == -12
True
>>> -12 is -12
False
IOW, the literal expression -12 happens to construct a fresh
value/object each time CPython parses it.

'object' is the class of all objects just like 'int' is the class of all
integers. So no trouble at all.

Correct! Abstractions are generalizations of specifics. You can't
understand the generalizations before being bored with the specifics
first.
