[GRASS-user] managing mapsets in Python Scripts

Greetings

I’m doing to image processing and I have 2 questions regarding mapset management

1- How can I define an image destination mapset? I mean should I first define mapset (g.mapset) and run my functions or should I define in output the image@target_MAPSET?
2- How can I retrieve the current mapset? What is the grass modules to perform this?

Thanks for your help

define target mapset as current using g.mapset. You have write access
only to the current mapset.

2- How can I retrieve the current mapset? What is the grass modules to
perform this?

in bash:

eval `g.gisenv`
echo $MAPSET

in python

import grass.script as grass
grass.gisenv()['MAPSET']
