You should be able to retrieve any environment variable
like this, if it exists:
import os
env_var = os.environ["PATH"]
Environment variables use the colon, ':', to separate
entries so you can do this if you want a list:
env_var_list = os.environ["PATH"].split(":")
BTW, variable names are case sensitive in Linux. The
ones set by the system are normally all upper case.
That is not absolute in cases where variables are set
by 3rd party programs.
