The last function doesn't work. I have tried it in the Workspace and it worked.

Why I can't pass the challenge?

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

def first_and_last_4(iterable):
    return first_4(iterable) + iterable[-4:]

def odds(itera):
    return itera[1::2]

def reverse_evens(itera):
        evenItera = itera[::2]
        return evenItera[::-1]

You are close! The last function is mixing spaces and tabs. It’s best to only use 4-space indentation.

Post back if you need more help. Good luck!!!
