Well, yes, probably.

My bad.  I got links mixed up -- it wasn't the first one, it
was this one:

http://www.faqts.com/knowledge_base/view.phtml/aid/3298

There are two almost-equivalent tirival answers:

  os.environment['foo'] = 'bar'

  os.putenv('foo','bar')
  
I don't get why people seem to be obfuscating things with
multiple layers of shells or writing shell commands to to a
file and executing them.

No, I mixed them up.

My point: the OP wanted to know how to export an environment
variable to a child process.  Either of the lines of code above
will do that, so what's with all the shellular shenanigans?
