# What's wrong with reverse_evens function?

I used [::-2] to slice and get the characters reversed with even indexes. I tried separately with the string "arunpatel". I got the value as ['l', 't', 'p', 'u', 'a']. I assumed same should have worked here.

slices.py
```def first_4(str1):
str2 = list(str1)

if len(str2) >= 4:
list1 = str2[:4]
else:
return
return list1

def first_and_last_4(str1):
str2 = list(str1)
if len(str2) >= 8:
list1 = str2[:4] + str2[-4:]
else:
return
return list1

def odds(str1):
str2 = list(str1)
list1 = str2[1::2]
return list1

def reverse_evens(str1):
str2 = list(str1)
list1 = str2[::-2]
return list1
```

The issue is being able to handle inputs that have both an even and odd number of items. If you try "arunpate", you'd get `['e', 'a', 'n', 'r']`. Think about breaking the problem into two parts. 1) extract the even index items, then 2) reverse this sublist.
