I was asking because in my notes in Org Mode, I am used to create
subheadings for each question I have. Here's an example:

Let's say that in my notes on Python, I have the following content

#+begin_src org
,* DONE How to get the number of lines in a file?
  - State "DONE"       from              [2021-02-16 Tue 20:02]

,#+NAME: create-file
,#+begin_src dash :results silent
cat << EOF > main.txt
first
second
third
EOF
,#+end_src

,#+begin_src python
print(len(open('main.txt').readlines()))o3
,#+end_src

,#+RESULTS:
,#+begin_example
3
,#+end_example

,* DONE How to print most repeated word in a file?
  - State "DONE"       from              [2021-02-16 Tue 20:02]

,#+NAME: create-file
,#+begin_src dash :results silent
cat << EOF > main.txt
fizz fizz fizz
buzz buzz buzz buzz
foo
bar bar
EOF
,#+end_src

,#+begin_src python
import re
from collections import Counter

with open('main.txt') as f:
    passage = f.read()

words = re.findall(r'\w+', passage)

word_counts = Counter(words)

print(word_counts.most_common(1))
,#+end_src

,#+RESULTS:
,#+begin_example
[('buzz', 4)]
,#+end_example
#+end_src

As you can see above, there are two code blocks which creates two text
files so that a Python script can then process it. Both of them create
a text file, that's why I have used =create-file= as the name of those
code block. I could have used very long names but I don't find
comfortable myself doing that since it adds extra effort to think in a
name for such simple code blocks (see below an example of the approach
of using long names).

#+begin_src org
,* DONE How to get the number of lines in a file?

,#+NAME: create-file-for-counting-lines
,#+begin_src dash :results silent
cat << EOF > main.txt
first
second
third
EOF
,#+end_src

,* DONE How to print most repeated word in a file?

,#+NAME: create-file-for-finding-most-repeated-word
,#+begin_src dash :results silent
cat << EOF > main.txt
fizz fizz fizz
buzz buzz buzz buzz
foo
bar bar
EOF
,#+end_src
#+end_src
