[GRASS-user] listing raster maps as input for "i.group"

[Stefan Lüdtke]

Hi Umberto,

I used to use it by extending the function with ".keys()", what does
return a list. But there might be smarter way than that.

code:

data_list=grass.parse_command('g.mlist', typ="rast").keys()

type(data_list)


HTH,

Stefan
