Thanks, but the last bit of your post ("...most of which have the
ability to run by themselves") makes me wonder whether we mean the
same thing when we talk of "scripts."  Can you give me an example
of a script that *does not* have the ability to run by itself?
When I use the word "script" I mean, *by definition*, a piece of
code that has the ability to run by itself.

I know that in the python world the distinction between a script
and a (library) module is not so clear-cut, and it is common for
library modules to have "top-level" stuff (typically test code)
that gets run if the module is invoked directly from the command
line.  But this is not *really* a script as I understand it, because,
even though it "runs" directly from the command-line, it lacks the
typical CLI amenities, such as command-line flags, help messages,
diagnostic messages that are aimed to the "naive user" (i.e. as
opposed to the developer), etc.  The coding of these "CLI amenities"
is one of aspects of these "exemplary Python scripts" I'm most
interested in learning about.

Anyway, thanks, I'll poke around in the standard library...
