Getting the correct solution in local system but treehouse says "Didn't get the correct results"

In the return_evens function, when I test it on my system from command prompt it works but when i check work on treehouse it says incorrect.

def first_4(item):
    return item[0:4]

def first_and_last_4(item):
    items1 = first_4(item)
    items2 = item[-4:]
    return items1 + items2

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

def reverse_evens(item):
    return item[-1::-2]

Hi Omprakash,

You are not trying a sufficient variety of inputs. Your function may work with odd-length lists, but what about when you try even-length lists?
