Ah, right, I forgot the surface reference (you don't have to draw to the screen, but can draw to any surface object) and reversed the color and rect parameters. Some of the other things being asked about are basically one-or-two-liners. Loading and displaying an image (by one method), for instance: pic = pygame.image.load("filename.png").convert() ## convert() is optional pic.set_colorkey((r,g,b)) ## Treat this color as transparent; good for images on a background marked with a weird color like (255,0,255) screen.blit(pic,(100,0)) ## Draw it at (100,0) For a sprite you can use general Python knowledge to make a class that has references to a loaded image and to a set of coordinates, then use the logic section of whatever main loop you've established to define rules for where the sprites move to, and to draw each sprite wherever its coordinates say. The pygame.sprite module contains methods for logical groupings of sprites and there's been discussion about collision detection methods. I don't like the sprite module myself, because it doesn't do much and it assumes that screen coordinates are the same as world coordinates. Instead I built a sprite module focused on defining a set of rect objects representing the frames of animation within a larger image, then having my sprite objects reference which frame should be displayed. For a main game loop you need some kind of loop that draws everything, handles events, and does some game logic like deciding what moves where and whether the game is over yet. In general you should look at the documentation on pygame.org, and try the built-in help commands help(thing_you_want_help_on) or dir(thing) to see what functions are available and how they work.
