That's an excellent question!
If pygame.init() is missing, you'll likely run into issues and errors when you try to use various Pygame functions later in your code.
Think of it like this: pygame.init() prepares all the necessary internal components of Pygame (like handling graphics, sounds, input events, etc.) so they are ready to be used. If you don't call it, these components won't be set up, and operations that rely on them will fail.
For example, trying to create a display surface (pygame.display.set_mode()) or load an image or sound without pygame.init() would result in errors, often telling you that Pygame hasn't been initialized or a particular module hasn't been started.
So, while it might seem like a small line of code, pygame.init() is crucial for ensuring that your Pygame application runs smoothly!
