I dont understand the challenge.. iterable function challenge

Hi, I dont understand the challenge, I wrote exactly what he said but he wanted kaoa as the result. what did it mean?

slices.py 
def first_4(iterable):
  return iterable[:4]

def odds(iterable):
  new_item=[]
  for item in iterable:
    if iterable.index(item)%2==0 :
      continue
    new_item.append(item)   
  return new_item

The "kaoa" is just the expected result of one of the challenge's internal tests. What's significant is that the expected result was a string but your function built and returned an array.

:point_right: Hint: this challenge is about using slices.

If that hint isn't enough, you might want to review the Slicing With A Step video.
