I found https://docs.python.org/3.7/tutorial/controlflow.html#the-range-function section 4.3 confusing. The range() Function shows the following example:

>>> for i in range(5):
...     print(i)
...
0
1
2
3
4

[some instructional text]

range(5, 10)
   5, 6, 7, 8, 9

range(0, 10, 3)
   0, 3, 6, 9

range(-10, -100, -30)
  -10, -40, -70

This appears to be an instruction to type, for example:
range(5, 10)
at the prompt, and that the response will be:
   5, 6, 7, 8, 9

leading to a perceived bug when I type at the prompt:
>>> range(5, 10)
and receive the response
range(5, 10)

I ultimately figured out that the example is a shorthand to substitute
range(5, 10)
for the original 
range(5)

>>> for i in range(5, 10):
...     print(i)
...
5
6
7
8
9

It would be less confusing if the example instead read:

----------------------------

Substituting "range(5, 10)" for "range(5)" results in (one number per line)
5, 6, 7, 8, 9

Substituting "range(0, 10, 3)" results in
0, 3, 6, 9

and substituting "range(-10, -100, -30)" results in
-10, -40, -70

---------------------------

such that it is clear that the statements are not meant to be taken as literal stand-alone entries to be typed at the prompt but are instead substitutions.

This block is the same in 3.9 and 3.8.

My first though is this block is a holdover from 2.7, where range returned list.  But looking at what is written previously, I think your interpretation is correct -- and agree that something other that code and corresponding output in a code block is confusing.  So this might better be a list than a code block.  Cheryl, do you have an idea of what might be better?

Another alternative is to make the example *be* interactive.
This would also teach the easy, standard, and often better way to see the output of an iterable.

>>> list(range(5, 10))
[5, 6, 7, 8, 9]
>>> list(range(0, 10, 3))
[0, 3, 6, 9]
>>> list(range(-10, -100, -30))
[-10, -40, -70]
