[GRASS-user] How to obtain list of all raster maps

[Micha Silver]

You can use the grass.script module 'read_command' to save the output of 
commands. i.e.


In [1]: import grass.script as gscript

In [2]: rast_list = gscript.read_command('g.list', type='rast', 
mapset="shkharia").strip().split('\n')

In [3]: type(rast_list)
Out[4]: list
In [5]: rast_list
Out[6]: ['aspect_4m', 'dtm_08_4m', 'dtm_4m', 'geomorph', 'shade_4m', 
'slope_4m']

Typically the output will be a string (or dict), but calling split('\n') 
breaks it into a list.
