Range in appleevents is a record (Python = dictionary) with the keys 
'star' and 'stop' and the values object specifiers. Python simplifies 
this to slightly in that you only have to specify the objects. So 
your line should read (and I haven't tested this):-

>>>>  db.get_data(record(Range(cell(1),cell(3)))
