[GRASS-user] Catch errors from grass.mapcalc

GRASS GRASS user

Greetings

I have python script where I try to catch, as much as possible all errors, in order to avoid “abrupt” ERRORS from the script.
for instance I do this for grass.run_command:

p=grass.run_command(“i.group”, group=group_name, subgroup=“subgroup”, input= input)
if p!=0:
grass.fatal(_(“ERROR MESSAGE”))

but I’m not being able to do this for grass.mapcalc. has anyone any suggestion or tip on how to do this for grass.mapcalc?
Thanks

Kim
