Sorry I bailed on you last night, but you know it's bad when you can't
read anymore.
I read through this today and saw several things I really need to work
with more, especially dicts, sets, generators and the zip function. I've
used all of them in fairly typical forms, but it's the atypical ones

Thanks Steve for writing this, and I'll read it more carefully when my
illness gives my mind back to me.
I was actually a math major before I discovered computer science, and I
had to progress beyond machine language and assembler before I found the
subtle differences and more flexible boundaries

Thank you Nate, for all these sources to study. Python was very easy for
me to learn in 2 online courses, but it's been all uphill since then.
I've learned a lot and for that I'm grateful, but there's so much
farther to go.

If you're fuzzy about dictionaries in general, it might be a

No worries, Deborah.
Python is by most measurements a relatively easy/simple language to learn,
but there are always the dusty corners. If you've not already, I recommend
going through the online Python tutorial in it's entirety (
https://docs.python.org/3/tutorial/index.html).

You have to know what you're looking for:
6.2.5: List Displays
6.2.6: Set Displays
6.2.7: Dictionary Displays
And, then, click on the appropriate eleme
