What's wrong with my code?

I don't what I'm doing wrong challenge 3 of 4, but when I run my code in the terminal it works.

def first_4(hello): return hello[0:4]

def first_and_last_4(heyoo): return heyoo[0:4] + heyoo[-4:]

def odds(killers): return killers(0::2)

slices.py 
def first_4(hello):
        return hello[0:4]

def first_and_last_4(heyoo):
        return heyoo[0:4] + heyoo[-4:]

def odds(killers):
        return killers(0::2)

You are very close! Two parts to correct:

  • The killers slice syntax should use square brackets or braces [ ] not parens
  • You are returning all of the even indexes. How would you signify the odd indexes? Hint: change which index you start on.

Post back if you need more help. Good luck!!
