Pygame sprite.spritecollide()

In the following Test in line 133 onwards i am testing for collision between targets and the bullets. I am wondering why the target_hit_list is allways only one Target object? Is it because target_hit_list gets updated and new assigned in each loop, so it is allways empty as the next collision takes place?

Here is the link to the code.

pygame has another feature which checks for collisions between all sprites at once. (collidelistall) Try that...

something like this:

running = True
while running:

    check_events()
    update_player_position()
    collision_check()
    draw_all()

def check_events():

    for e in pygame.event.get():
        if e.type==pygame.QUIT or (e.type==pygame.KEYDOWN and e.key==pygame.K_ESCAPE):
            runs=0
        player.shoot()

def update():

      #logics
    for ahsm in all_have_same_method:
        ahsm.hanging()

    all_have_same_method.update()


def collision_check():

    for b in bullet_group:
        target_hit_list=pygame.sprite.spritecollide(b,target_group,0)
        for thl in target_hit_list:
            score+=1
        print target_hit_list #why is in the target_hit_list allways only one Target object? 

def draw():
    #drawings
    #draw score
    draw_score=font.render(str(score),True,RED)
    screen.fill(BLACK,(0,0,50,20))
    screen.set_colorkey(BLACK)
    screen.blit(draw_score,(0,0))

    all_have_same_method.draw(screen)

Yes. Also the bullet only collides with one target. Also you should separate the code out, so you have a main loop that goes like this, with each of these a function on their own:

check_events()
update_player_position()
collision_check()
draw_all()

Rather than have everything mushed together in the same area.
