Found this on stackoverflow(http://stackoverflow.com/questions/12433695/extract-elements-of-list-at-odd-positions), this code seems to satisfy the challenge:

def odds(arg):
  return arg[1::2]

In my opinion the challenge question isn't clear. I didn't interpret "returns the items with an odd index" to actually mean 'returns only the original list items whose indexes are odd'.

I understand now what he means, but it just wasn't clear the first 27 times I read it.
