What's the problem with my code?

Again, I cannot get it.

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

def first_and_last_4(iterable2):
    return iterable2[:4] and iterable2[-4:]

def first_and_last_4(iterable2):
    return iterable2[:4] and iterable2[-4:]

Remember how to join two lists together?

def first_4(iterable): return iterable[:4]

def first_and_last_4(iterable2) list1 = iterable2[:4] list2 = iterable2[-4:] newlist = list1 + list2 return newlist```

I have tried this but still not working

def first_and_last_4(iterable2):
    list1 = iterable2[:4]
    list2 = iterable2[-4:]
    newlist = list1 + list2
    return newlist

You're just missing the colon at the end of the first line, otherwise it works fine :)
