Research direction
Start with the Python snippet in the issue, especially the os.system('cls') and os.system('clear') alternatives. Reproduce the moving-text example in the relevant terminal environment and determine why the screen is not cleared; done means the exercise visibly clears the previous output while continuing the animation.
