[GRASS-user] g.rename problem with Python

[RichardCooper]

I' trying to rename a bunch of imported netCDF layers which include
periods/dots in their filenames. I can rename replacing the '.' with '_' in
the g.rename GUI module, but in Python I get the following errors.

I'd be really grateful for any advice on how to deal with the periods in the
Python script. Alternatively, I could rename before importing into GRASS...

Thanks,
Richard

My script is as follows:

from grass_session import *
...
 #Rename layers replacing '.' with '_'
with open('glist_llrotate.txt') as gl:
    for line in gl:
        renamed = line.replace('.','_')
        print 'Renamed layer:', renamed
        grass.run_command('g.rename', raster = (line,renamed), overwrite =
True)
...

And the error: 
WARNING: Illegal filename <cahpa.f1jan.05216.nc_remapped.nc.27
         >. Character <
         > not allowed.

The gllist_llrotate.txt file contains content such as:
cahpa.f1jan.05216.nc.1
cahpa.f1jan.05216.nc.10
cahpa.f1jan.05216.nc.11
cahpa.f1jan.05216.nc.12
