Stuck on question 3.. How to return 1st 4 and last 4 numbers in iterable..

Question 3: Objective: Make a function name first_and_last_4 that accepts an iterable and returns the first 4 and last 4 items in the iterable.

# Test1 code
def first_4(iterable):
  return iterable[0:4]
# Test2 code
def odds(iterable):
  return iterable[1::2]
# Test3 code
def first_and_last_4(iterable)
list1 = iterable[0:4]
list2 = iterable[-4:]
  return list1 + list2

Nevermind... I stuck my head in the freezer for a minute and the answer came to me. :)

Actually I found it here.... (https://docs.python.org/2/tutorial/introduction.html)

I didn't need to create the variables. Just added the two iterables together.. Sometimes python is so simple it's complicated! LOL

What you have now should pass once you get the indentation correct.
