My implementation of the reverse_evens() doesn't seem to work. Could you review my function ?

def reverse_evens(list): return list[::-2]

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

def first_and_last_4(list):
first_4 = list[:4]
last_4 = list[-4:]
return first_4 + last_4

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

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

Hi Antoine,

You just need to change the `-1` to a `-2`. Like so, `[-2::-2]`. I tested this in the Python shell and it worked.

```Python 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:19:30) [MSC v.1500 32 bit (Intel)] on win32
>>> iterable = [1,2,3,4,5,6,7,8,9]
>>> iterable[-2::-2]
[8, 6, 4, 2]
```

However, the code challenge didn't accept it, so I tried the more verbose code below and it passed.

```def reverse_evens(iterable):
results = []
for i in range(0, len(iterable), 2):
results.append(iterable[i])
return results[::-1]
```

Let me know if you have any questions!

Hi Chris,

Thanks for commenting. I was going nuts with that particular issue.

Looking at Chris Jones's answer I figured I could just use the list copy() method

```def reverse_evens(list):
result = list.copy()
return result[-2::-2]
```

Actually i retested my solution and it didn't work. :-(

Oops :(. It could just be me, but I felt like the Python code challenges were the most picky of the languages I've learned through Treehouse. It seemed like most were looking for you to solve the challenge a specific way, rather than verifying your end result.
