Displaying an Animation#
The animation of the snake above is produced using the code for custom images. Each image is slightly different than the next image, and the sequence of images is repeated indefinitely in a while loop. Below are three equivalent programs that display the animation.
The first program uses the multi-lined custom image style and displays each image with a delay in the
whileloop.The second program uses the single-lined custom image style and displays each image with a delay in the
whileloop.The third program uses the single-lined custom image style and collects them in a
