Environment Variable

[tuxlover]

Is it possible to set an environment variable from inside the python
script which will be retained after the script exits.

If I use the following code:

import os
os.putvar("name", "tuxlover")

the enivironment variable name is visible to only the sub-process
created by os.system and os.popen. But as soon as the python script
vanishes, the environment variable "name" is gone.

What I am wondering is that is it possible to set a environment
variable from inside a python script, and then access it (say, echo
$name from the shell) after the python script exits.

Thanks
Tuxlover

No, I regret it is currently not. But I see a significant chance that
someone gets on the time machine and implants this into Thompson's head
some 30 years earlier as soon as you post that a third time.

Since it appears you are reposting the same question that started this
thread: were Grant's and Sybren's replies unsatisfactory and, if so, in
what way?

No, the replies from Grant's and Sybren's do answer my question. I
posted twice because my browser locked itself up, and I ended up typing
twice

It would be a lot more polite to actually thank the people helping
you.

Expressing gratitude is indeed a courtesy.

As an old-time Usenetter, I also have a high regard for
economy or brevity; I generally communicate my thanks in
private e-mail, unless I can embed them in a comment which
I think is likely to interest a wider audience. I have in
mind something on the order of, "Thanks, timbot! I notice
that not only does that solution conform to IEEE 754, as
requested, but it's compatible with the Rayleigh-Ritz
implementation found in ..."

I'm certain neither of Mr. Stuvel's point, nor of whether
it applied to tuxlover's actual behavior. I wouldn't want
readers to think, though, that every well-formed clp thread
must necessarily terminate in a follow-up whose content is
limited to "Thx."
