Hi all!
as reported in the new web page [0] of the pyGRASS project, at the moment you
can interact with a raster map in this way (read-only): ::
# import the raster function
>>> import obj
# instantiate a Raster
>>> dtm = obj.Raster('dtm')
# open the raster in read mode 'r'
>>> dtm.open()
# get access
>>> for row in dtm[:5]: print(row[:3])

>>> dtm[5][:3]
[718.051025390625, 717.7310180664062, 717.4210205078125]
>>> dtm.close()
Any hint or suggestion are welcome! The Raster class use only the grass ctypes
library.
