Could someone check my work? Wow, that was that a challenge! I spent over an hour working on it, lol. I got a green check, but I have no idea if I did it correctly or if I just got lucky. I basically played around with it and did some math to try and figure it out.

#Write your function here

def double_index(lst, index):

if len(lst) >= index + 1:

change_int = lst[index] *2

new_list = lst[0:index]

new_list.append(change_int)

```
index3 = index + 1
append_list = lst[index3:]
return new_list + append_list
```

else:

return lst

#Uncomment the line below when your function is done

print(double_index([3, 8, -10, 12], 2))

I did a little googling to try and find out how to do it. I didn’t cheat, I was just looking for different ways to append and combine lists. I saw a command insert(). Could that have been used as an alternative?
