I do get the difference.  I don't actually use Python 2.  I use
CodeSkulptor.  I do have Python 3 installed.  Actually I have Python 2
installed but IDLE defaults to Python 3.  So it is a pain to actually
load Python 2.

Range(10) stores the min max values and loads each number in between
when needed.  Ian explained that very clearly.

I tried list(range(10)  I thought that would work in Python 3.  It
didn't.  I spent quite a bit of time last night trying to come up with
the right combination of str and int commands to make range(10) work
with my simple example.   It didn't.  I am pretty frustrated.  I am
just skipping that little bit of code for the moment.

Thanks everyone for your suggestions.
