# Why isn't this working

Here is my code.

def first_4(new_list): return new_list[:4]

def first_and_last_4(new_list): temp_list = new_list[:4] temp_list2 = new_list[-1:-5:-1] temp_list.extend(temp_list2) return temp_list

The challenge wants me to return the first and last 4 digits of a number and return them as a single value.

I plugged it into my python IDE and the code for the first_and_last_4 function work correctly.

What am I missing?

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

def first_and_last_4(new_list):
temp_list = new_list[:4]
temp_list2 = new_list[-1:-5:-1]
temp_list.extend(temp_list2)
return temp_list
```

One issue with testing challenges in external REPL's is that it's easy to misinterpret the goal, which seems to have happened here.

The instructions for the "first_and_last_4" function do not say that the last four should be returned in reverse order. Extract the last four in the original order and you should pass the challenge.

I thought of that. And just tried adding the following line to reverse the order.

temp_list2 = temp_list2[::-1]

However, it keeps telling me that the wrong numbers are being returned by first_and_last_4. Or are you saying I need to get the last four in the right order from the on set?

Thanks for your help.

Neeeeverrrr mind. Turns out I was using append() when I needed extend().

Again, thank you.

The original solution above does use `extend`, but it also had a negative step in the slice.

Anyway, glad to help. And happy coding!
