# Why does the prompter tell me that my solution is incorrect however is reviewed my answer and it returns the correct val

I am having a problem with reverse evens specifically. I am supposed to return a list that is the reversal of the original and only the even indexes of that list. However after i completed the task it tells me it is incorrect.

slices.py
```def first_4(whatever):
return whatever[0:4]

def first_and_last_4(single):

final = single[0:4]
final.extend(single[-4:])
return final

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

def reverse_evens(single):
reverse = single[::-1]
final = []
for item in reverse:
if(reverse.index(item) % 2 == 0):
final.append(item)

return final
```
