While I don't understand your questions, I suspect the series I've launched
with <URL: http://www.samag.com/documents/s=8964/sam0312a/0312a.htm > will
interest you.

When you write, "Can I export a variable ...", are you asking that the
result of an external process be bound to a Python name (or variable), OR
that a Python process export a "shell" variable to its environment, OR
...?
