You must call the Sprite.__init__ function from your own classes __init__.

Ok, this is weird:

screen = pygame.display.set_mode((500, 500),pygame.NOFRAME)

bgc = 0, 255, 2

#make a canister

spritecan = pygame.sprite.Group()


redcar = basicsprite("redcar.png")
spritecan.add(redcar)
#ready... set... GO!!!

while True: #main loop
    clock.tick(30)
