Hi again, - replace the python script with the following (apologies
version confusion):
#!/usr/bin/env python
#-*- coding:utf-8 -*-
from grass.script import core as grass
from grass.script import db as grass
from grass_session import Session
from grass.script import core as gcore
# create a new location from EPSG code
with Session(gisdb="/Users/jon/a_tmp", location="a_tmp_location",
create_opts="EPSG:3057"):
print '-'
# create a new mapset in an existing location
with Session(gisdb="/Users/jon/a_tmp", location="a_tmp_location",
mapset="a_test", create_opts=""):
print '--'
