bam! that is the part that I was missing.
I kept thinking "a tuple is read only. I can see the value in that, but there
has to be more to it then that."
I kept having this feeling it was like 2 kinds of string construction:
x='c'+'a'+'r'+'l'
x='carl'
"one of those is pointless!"
And all those thoughts seemed so out of line with the rest of Python.
