Hi Nikos,
You could use numpy and genfromtxt() to parse the output string...
genfromtxt() requires an StringIO object (or file) and StringIO (from io)
requires unicode()...
So you could do:
from io import StringIO
import numpy as np
output = np.genfromtxt(StringIO(unicode(grass.read_command('r.category',
map=base))) , delimiter='\t', dtype=None, names=['cat', 'label'])
That causes however some overhead [1]. So if it makes sense depends on what you
want to do with the data in the further processing chain...
Cheers
Stefan

Thank for the idea Stefan. This is really a small (in size) task. I think it's not worth to use NumPy just for a few lines. Wouldn't the major reason, to use NumPy, be speed in computations? Nikos
