You could do something like:

---------------------------------
#!/usr/bin/python

import grass.script as grs

# get info about my location and mapset
env = grs.gisenv()
pathbase = env['GISDBASE']
location = env['LOCATION_NAME']
mapset = env['MAPSET']

# get absolut path to actually mapset
pathmapset=path.join(pathbase, location, mapset)

# get rasters
rasters=grs.list_grouped('rast')
# get vectors
vectors=grs.list_grouped('vect')

------------------------------------

may be there are something better...
