Difficulties with Challenge first_and_last_4. What is wrong with my code?

Hi everyone! I'm not sure why I cannot pass through Task 2: first_and_last_4. I wrote my code in the Workspace and it gives the result I'm searching for. What did I do wrong?

def first_4(old_list):
    new_list = old_list[:4]
    return new_list

def first_and_last_4(old_list2):
    new_list2 = old_list2[:4] + old_list2[-1:-5:-1]
    return new_list2

Already solved. I made a code new_list = old_list[:4] + old_list[-4:] and it was correct.
