What are they asking me for in this challenge?

I don't understand the instructions of this challenge very well, are they asking me to return the value of any odd index item in the iterable?

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

def odds(opa):
  return

Hi Wilfredo,

It wants all odd indices returned. For example, if the string "Hello" was passed in then it should return "el" which are the characters at indices 1 and 3 respectively.

This video and the teacher's notes below it should help if you're not sure how to slice the iterable to achieve this.
