Hi there! You did it just beautifully. However, you were meant to alter the first loop in the second step instead of making an entirely different loop. Now it's printing all the things from the first step plus the things from the second step. Removing the first loop causes this to pass Step 2.

Hope this helps! :sparkles:

Hey, thanks I have done that it worked, yes it has helped.
