As Chris has said, the os module is the way to get and modify the
environment of your Python program, whether on Linux or elsewhere.
However, the wording of your question was ambiguous enough that I
thought I'd better clarify. Changing the environment within one
application does not in general affect any other. So if you had
thoughts of setting an environment variable from your python script, and
exiting, and having the next thing you ran from the shell affected,
better think again.
That sort of thing needs to be done from the shell, rather than from a
script. And while there are tricks to do, they're Linux-- (or Windows,
or whatever) tricks, not Python ones.
