Yes. Thank you, and everybody else. I'm still learning, and still
getting used to Python. But, I understand the concepts that I was
having trouble with before.

Actually, I have programmed in many languages. I just first learned in
Pascal.
For me, going from Pascal, to basic,c,cobol,fortran . . was not that
difficult. Python, however, feels strange.
As crazy as this may sound: Python, in some ways, reminds me of

Dude! Did you miss the Original Poster's VERY FIRST SENTENCE???

He's thinking in Pascal, not

FWIW, booleans were a late add-on. Originally, Python didn't had a bool
type, only rules about the boolean value of a given object, mostly: 0,
0.0, '', [], (,), {} and None

Python doesn't have variables. It has objects to which you can
bind names.

a = list("1234")
That creates a list object and binds the name "a" to it.

I learned to program with Pascal, way back when. Went into software
development for a while, then went into systems admin. Have programmed
in several languages, just learning Python.
Some things I find odd:
1) 5/-2 == -3?
2) list assignment handling, pointing two vars to the same list:
