I keep getting the error Couldn't find `first_and_last_4`. I just can't see where I am going wrong.

.

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

def first_and_last_4(iterable):
    return interable[:4] + iterable[-4:]

Hi there,

You're returning interable not iterable. The rest is fine! :smile:

Steve.

We ALL spend too long looking at typos and not seeing them. It's just the way it is! :+1:

I'd love to say it gets better with time. In my case, that's not true. :wink:
