Thank you for the technical explanation. "print a,b" is nice to read
in simple Python programs. But when you need to get more control of
I/O it's better to know what's really happening inside.

So the "softspace" is always added after a "print a," statement but only
printed if Python thinks it is not at the beginning of a terminal line.
Interesting.

Again, thanks. I'll rest my case.
