Environment variables can be accessed using e.g.:
gisbase = os.environ["GISBASE"]
or:
gisbase = os.getenv("GISBASE")
The main difference between the two is that the former raises an
exception if the variable doesn't exist while the latter returns None
(or a user-defined value specified by the second argument).
$GISRC variables (GISDBASE, LOCATION_NAME, MAPSET) can be accessed via
grass.script.gisenv(), e.g.
import grass.script as grass
env = grass.gisenv()
mapset = env["MAPSET"]
