Why is it saying it cant find first_and_last_4?

This should pass as it works on my console

def first_4(iterable):
    iterable_list = list(iterable)

def first_and_last_4(iterable2):
    iterable_list2 = list(iterable2)
    first_four = iterable_list2[0:4]
    last_four = iterable_list2[-1:-5:-1]

    mergedlist = []
    return mergedList

It seems like some sort of a bug. However this is my approach to this challenge which will allow you to pass it:

def first_and_last_4(a):
    result = list(a[0:4])
    return result

One thing that I would mention is that variables created inside functions are only available inside those functions, so you don't really need to make names like iterable_list and iterable_list2. Both functions can use iterable_list.
