Make a function name first_and_last_4 that accepts an iterable and returns the first 4 and last 4 items in the iterable.

I can't quite figure out why this wont run. I have my index going for 0-3 (or 1-4) and my negative at -4.

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

def odds(idx):
idx = "Oklahoma"
return idx[1::2]

def first_and_last_4(idx):
idx(range(0, 50)
print idx[:3] + idx[-4:]
```

Your code should look something like this:

```def first_4(iterable):
return iterable[0:4]

first_4([66, 333, 222, 1, 1234])

def first_4(iterable):
return iterable[0:4]

first_4([66, 333, 222, 1, 1234])

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

def first_and_last_4(iterable):
return first_4(iterable) + iterable[len(iterable)-4:]
```
