or simplier: module.outputs.stdout
or using directly the C API through python with:
{{{
from grass.pygrass.vector import VectorTopo
from grass.pygrass.raster import RasterRow
from grass.pygrass.gis.region import Region
with RasterRow('elevation', mode='r') as rast:
with VectorTopo('hospitals', mode='r') as hospitals:
region = Region()
for hosp in hospitals:
value = rast.get_value(hosp, region)
if value is not None:
print(hosp.cat, value)
}}}
