This is what I've come up with so far, it looks like garbage I know.
On the contrary its not too far away.
But we'd rather see a garbage first attempt than no attempt
at all, at least we then know where the problems lie!
list1 = [1,2,3,4,5,6,7,8,9]
list2 = [100,200]
final_list2 = []
You don't need the final_list here
def transform(list1, list2, r1, r2):
temp_list = list1[4:7:-1]
final_list2 = list2.append(temp_list)
But you should *return* this value here. This is creating a new local
variable inside the function, it's not using the global value
you defined above. Also since append() (and extend() for that matter)
do not return a list value final_list2 will always equal None. You
are modifying list2 directly.
Others have commented on the other code inside the function.
