Here's my solution:

rainbow = ['red', 'orange', 'yellow', 'green', 'blue', 'indigo', 'violet']

for i in rainbow:
    print(i)

The for loop is what we are using to go over the items in the list. We are needing to output the index of the item in the list and the value i has this. Then we just need to print that out. Hope this makes sense and feel free to ask any questions
