# Thought this should work?

With reverse evens, the first colon is to accept the whole iterable; the second one is for even numbers only and the last one is to reverse it

slices.py
```def first_4(thing):
return thing[0:4]
def first_and_last_4(thing):
return thing[0:4] + thing[-4:]
def odds(thing):
return thing[1::2]
def reverse_evens(thing):
return thing[::2:-1]
```

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

Seems not to work

Slices are start - step - stop.

You should be able to do thing[:-2:-1]

What exactly are you expecting from that function?

Thanks @Cole Wilson for the reminder. I figured it out, had to separate the 2 steps and then it worked fine.

def reverse_evens(thing): return thing[::2][::-1]

Thank you everyone for the help!
