def reverse_evens(something):
    copy_of_something = something[::-1] #reversing 
    return copy_of_something[::2] #returning every second value

Task is print items at even index values in reverse order

what wrong am I doing here?

slices.py 
def first_4(arg):
    arg1 = arg[:4]
    return arg1
def first_and_last_4(something):
    result = something[0:4] + something[-4:]
    return result
def odds(arg):
    result = arg[1::2]
    return result
def reverse_evens(something):
    copy_of_something = something[::-1]
    return copy_of_something[::2]

Hi Srikanth,

You almost have it. The key to this is in the wording of the challenge. Basically it wants you to return the even indexes in reverse. In other words, get the even indexed items first, then reverse them.

While your code is very close, it is actually doing the opposite. It's reversing the list first and returning the even indexes of that.

Hope this helps.
