Thanks again, Terry. There is a lot to the language, I am finding
out. I am a HW engineer, not really a programmer. Python seems a lot
more sophisticated than MATLAB.
I'm kinda thinking `write` is likely to be a little more "stable" than
`print` (if that is the right characterization) when my eventual
switch from 2.7 to 3.x happens. You think?
