The challenge wants you to replace the first for loop for the one with enumerate and then add another print statement to output the item:

for index, current_element in enumerate(rainbow):
    print(index)
    print(current_element)

Guys, I found the answer the way to solve the second question is pretty easy, here is the solution

rainbow = ['red', 'orange', 'yellow', 'green', 'blue', 'indigo', 'violet'] 
     for index, current_element in enumerate(rainbow, 0):
           print(f'{index}. {current_element}')

you just need to change the enumerate starting value to 0 instead of 1

That gets the result, but it's not done the way the instructions asked for.

This can work also.

rainbow = ['red', 'orange', 'yellow', 'green', 'blue', 'indigo', 'violet']
for index,color in enumerate(rainbow):
    print(index)
    print(color)

The instructions say "Edit the code so that the for loop uses the enumerate method." So unlike most challenges, you will change the task 1 code instead of adding another loop.

The rest of the instructions say "Add a print statement above the existing print statement that prints the index of the current element." So the new print should print only the index. The other one will still print the value.

This is how I got it to pass not sure if its intended or not Steven Parker can verify.

rainbow = ['red', 'orange', 'yellow', 'green', 'blue', 'indigo', 'violet'] for item in enumerate(rainbow): print(f'index') print(item)
