improve example.py's output readability

Instead of just writing the sections as comments in the source, now it prints that to the output as well, using:

print(f"""
====================
Section
====================""")

Sorry but I don't find a good reason to merge this, and can think of reasons to not merge PRs like this.

No problems. I just wonder why you don't see this enhance the readability?

The example script is not meant to be executed, there's no point in adding print statements.

Also, now that there are tests I think it's obsolete and will be removed in the future.
