Does anybody has an example grass python script that deals with
multiple layer input? For example with the input option below with #%
multiple set to yes, I would like to create multiple variables, one for

I am completely new to python, and besides python scripting tutorials
and text books, for me using examples is a great way to accelerate the
learning process. I have looked into the addon repository and scripts in
the GRASS 7 SVN, but haven't found what I was looking for.
More in general, does anybody have (simple) shell scripts that have now
been converted in python scripts? I thought I had seen a page on the
grass wiki where code snippets in shell and python were compared, but I
can't find it.
You can always look at the scripts in grass7. A quick grep through the
directory shows:
i.spectral/i.spectral.py
r.buffer.lowmem/r.buffer.lowmem.py
r.in.wms/r.in.wms.py
v.db.addtable/v.db.addtable.py
v.db.univar/v.db.univar.py
v.in.wfs/v.in.wfs.py
v.krige/v.krige.py
Generally, you should be able to do something like this:
rastermaps = input.split(',')
and the access each maps like this:
my_map1 = rastermaps[0]
etc
