This idea elif x == funky_empty: result = 'no data'
Can be accomplished with if not len(items): result = 'no data' which means that part of the proposal can be scratched IMHO.
Not quite: len(items) requires iterating across the entire list which may not be necessary or desirable. Plus you may need an intermediate variable to store it. I think that's inferior.
If len(items) requires iterating across the entire list, then you're not using a Python list object, you're using someone else's (poorly implemented) list data structure. Python lists give len(obj) in O(1).
