Task about using slices-solution not passing the challenge.

In python collections course I am stuck with the following task:

Challenge Task 2 of 4: Make a new function named first_and_last_4. It'll accept a single iterable but, this time, it'll return the first four and last four items as a single value.

My solution gets a 'bummer' for the following solution: If item2 = 'kukeleegu' then my solution gives 'kukeugee' and if item2 = [1,2,3,4,5,6,7,8,9] then 12349876. I believe that these are correct answers and solution should be bassed but I will get a 'bummer', why ? Can anyone help me with that ?

def first_and_last_4(item2):
    uus=[]
    for i in item2:
        character=str(i)
        uus.append(character)
    string1 = ''.join(uus) 
    return string1[0:4:1]+string1[-1:-5:-1]

It looks like you're reversing the order of the last 4 items, but the instructions don't ask for that. Just return the first and last 4 items in their original order.

Thanks for the comment Steven! Yes the last four were backwards, but still the solution is not passed. I re-posted the issue in a better form.
