[GRASS-user] r.sun in python loop

First, you need to set some environment variables:

export GISBASE="/usr/local/grass-6.4/"
export PATH="$PATH:$GISBASE/bin:$GISBASE/scripts"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$GISBASE/lib"
# for parallel session management, we use process ID (PID) as lock file
number:
export GIS_LOCK=$$
# path to GRASS settings file
export GISRC="$HOME/.grassrc6"


After that in the Python Shell:

   import grass.script as grass
   gisbase = os.environ['GISBASE']
   gisdb="/path/your grassdata"
   location="your location"
   mapset="your mapset"
   import grass.script.setup as gsetup
   gsetup.init(gisbase, gisdb, location, mapset)

and you are working in the chosen location and mapset 
# for example list of vectors
res = g.parse_command("g.list", _type="vect")
for elem in res:
       print "element:" +elem
etc.
