Hello grass users!

I am quite new to use grass gis via a python script from outside.
I am runnning grass gis on windows and I can call grass.script in python.

After reading the grass-website about python scripts, I still don't know how to start. I just want to create a .py file which i than want to run.

This python script should do following simple grass command:

v.to.rast input=river output=river_raster use=val value=1 --o

but how does a pyhton script look like for this command?
I first need to define my location and my mapset and I have to import or define somehow the variable river. How do I set the region? In Grass I just do g.region vect=river res=10 save=region_river.

Can someone just give me an example for these two commands and how such a .py will look like...

Thank you very much
