 Here the method `pygame.font.SysFont` creates a font object, which uses the system font Arial in size 24. The the method `render` creates an image of the specified text in the given colour. This image is drawn on the window with the `blit` method, just as before.

If the system this program is exeuted on doesn't have the Arial font, even though Arial is a very common font available on most systems, the default system font is used instead. If you need to have a specific font available for your game, you can include the font file in the game directory and specify its location for the `pygame.font.Font` method.
