'Cannot see bullets when game is running

You have to draw the bullets after drawing the background. Use a loop to iterate through the list of bullets and call the draw_bullet method for each bullet:
while running:
# pygame.display.bullet() <--- DELETE
spiller.farty = 0
spiller.fartx = 0
trykketliste = pygame.key.get_pressed()
spiller.skytt()
background_image_1 = pygame.image.load("beach.png").convert()
screen.blit(background_image_1, [0,0])
# INSERT
for bullet in spiller.bullets:
bullet.draw_bullet()
# [...]
pygame.display.update()
# [...]
screen.blit(background_image_1, [0,0]) draws the background and hides anything previously drawn. pygame.display.update() updates the display and makes everything that is drawn visible. Therefor you need to draw all the objects of the scene after screen.blit(background_image_1, [0,0]) and before pygame.display.update().
