first_and_last_4 challenge

i dont get how to get this. the way that i am doing it, is im creating two difference slices but thats not what is asking me to do. i have to slice the first 4, and the last 4, all in one slice

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

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

def first_and_last_4(str):
  return str[0:4],str[-4:]

Can you try 2 slices, then concatenate them with the + operator?

return str[:4] + str[-4:]
