# Why is my answer still wrong?

The solution is correct but it won't let me continue because it tells me that the solution is wrong. although i tested the code and it returns exactly what it is asking for. This problem is specific to the problem of reverse_evens problem

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

def first_and_last_4(items):
first = items[:4]

second = items[-4:]
first.extend(second)
return first

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

def reverse_evens(items):
return items[-1::-2]
```
