For me it works like:

rasters=grass.read_command('g.list', type='raster', separator='comma').split(',')

I wonder why the 'comma' is not mentioned for the separator option, when
asking for the module's help:
```
Lists available GRASS data base files of the user-specified data type optionally using the search pattern.

Usage:
 g.list [-iretmpf] type=datatype[,datatype,...] [pattern=string]
   [exclude=string] [mapset=name[,name,...]] [separator=character]
   [region=name] [output=name] [--overwrite] [--help] [--verbose]
   [--quiet] [--ui]

Flags:
  -i   Ignore case
  -r   Use basic regular expressions instead of wildcards
  -e   Use extended regular expressions instead of wildcards
  -t   Print data types
  -m   Print fully-qualified map names (including mapsets)
  -p   Pretty printing in human readable format
  -f   Verbose listing (also list map titles)

Parameters:
       type   Data type(s)
              options: raster,raster_3d,vector,label,region,group,all
    pattern   Map name search pattern (default: all)
    exclude   Map name exclusion pattern (default: none)
     mapset   Name of mapset to list (default: current search path)
  separator   Field separator
              default: newline
     region   Name of saved region for map search (default: not restricted)
     output   Name for output file
```
