I've suggesting seeing 8 as a name only briefly, temporary gestalt
switch, then go back to seeing it as a literal, kind of like a name
in that you can do dot notation on it, i.e. there's an underlying
object that's responsive to these triggers (like 8 .__add__(5)
instead of just 8 + 5). But is the underlying object "anonymous"?
It has a memory location:
id(8)
12015636
id('8')
13259744
And I'm able to refer to it. I didn't make up a name for it, like
eight, because I didn't need to, it's already permanently
accessible through 8.
Numbers are just language syntax to create objects. If they aren't assigned
a name, they disappear.
x=1000
y=x
z=x
y is z
True
x is the name of an object. y and z also are names for that object.
1000 is not a name:
x=1000
y=1000
z=1000
x is y
False
x is z
False
y is z
False
a new object is created each time.

P.S. Note, at least in CPython, that same example won't work for small
numbers because of an implementation detail that caches the common 'small
number' objects for performance reasons.
x=1
y=1
z=1
x is y
True
y is z
True
