That, I have edited as shown (except the snippet outputs). That was an example of using Org Babel. Note that the #+RESULT blocks in that file are all auto-generated; none hand-written.
That post does not have any #+INCLUDE because all the code snippets are trivial. I would use #+INCLUDE in posts where I have a code file, and I want to talk about only few lines from that.
I have different examples of #+INCLUDE in my examples file[1] for my Org to Markdown for Hugo exporter -- ox-hugo[2]. There I use the inbuilt INCLUDE feature where I choose to include only the specified Org sub-tree (using the sub-tree CUSTOM_ID). The above referenced post on Nim/Python is converted to Markdown for Hugo using the same exporter.
