I sent a reply to you (Charles-Henri) but only after I had replied to Jim
and (here's what took the time!) after I'd digested your contribution.
I'm in a hotel and the system barfed when I hit send!
The gist of the message was:

You've shown me the light!
I understand it now.
I think I am well on my way to figuring things out.

..and thank you very very much. I very much appreciate the time you took
to consider the issue.

This Python class is causing me to have to learn math that I haven't considered since long before graduation! (and I shudder to think how long that is as I am currently on my way back from a reunion.)
