You're going to want to use a slice. I used the slice [:4] to return the first four items of the iterable.

I'm not sure if this matters or not, but I didn't use any spaces in my argument when I did it. For example, something like this:

def first_4(iterable)

First, you can't have spaces in variable/parameter names.

Second, you should be returning the first 4 items in the array with the slice method, like this:

some_list[:4]

The colon in front of the 4 means that we want the 4th item (not the 5th item!) and all the elements before.

You can do similarly with the colon in front:

some_list[4:]

This will get the items starting from 4 and all the elements after.

So, to complete this task, you should do:

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

Good luck! ~alex
