This is incomprehensible jargon to some; is only (partly) true of 
(typical) machine-implementations; and seems not to be true of all 
objects. I believe that for CPython, builtin objects, including the 
fixed arrray of ints from -5 to 256, are allocated in another data 
segment (more CS jargon, which is irrelavant to human interpreters).

Evidence 1:
 >>> id(int)
505285072
 >>> id(str)
505233232
 >>> id(1)
505493792
 >>> id(-5)
505493696

This appears to be initialized data segment. (Someone else could take a 
white box approach and look at the source. ;-)

 >>> id(333333)
16512288
 >>> id('a')
11227616

This is heap.

Evidence 2:
Some error messages use 'heap type' to mean 'Python-coded class'

 >>> 1 .__class__ = str
Traceback (most recent call last):
   File "<pyshell#8>", line 1, in <module>
     1 .__class__ = str
TypeError: __class__ assignment: only for heap types

Would you say 'names refer to objects rather than containing them 
directly'? Surely not. Using 'name' rather than the hugely overloaded 
tern 'variable' automatically avoids certain misunderstandings.

A good summary might be "Python manipulates objects that are accessed 
through literals, names, and expressions."
