Thanks, that was the hint I needed.  (Apologies to Aahz--he knows why.)

The called program needs to write to stdout, the calling program needs to
read the output.  See the subprocess module.  For anything more
complicated, you need to think about what you want and how to go about
it, the general term for searching more info is "interprocess
communication".

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
