something about pygame:'Group' object has no attribute to 'rect'

It's my first time to ask questions.I'm making a game called "Alien Invasion" in python.When I want to click the "Play",it does't work.I keep on getting this error:

Traceback (most recent call last):
  File "alien_invasion.py", line 30, in <module>
  File "alien_invasion.py", line 24, in run_game
  Flie "D:\python_work\alien_invasion\game_function.py", line 38, in check_events
  Flie "D:\python_work\alien_invasion\game_function.py", line 41, in check_play_button
AttributeError:'Group' object has no attribute 'rect'

This is my code about game_function:

def check_events(ai_settings,stats,play_button,screen,ship,aliens,bullets):
    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            sys.exit()
        elif event.type==pygame.KEYDOWN:
            check_keydown_events(event,ai_settings,screen,ship,bullets)         
        elif event.type==pygame.KEYUP:
            check_keyup_events(event,ship)
        elif event.type==pygame.MOUSEBUTTONDOWN:
            mouse_x,mouse_y=pygame.mouse.get_pos()
            check_play_button(ai_settings,screen,ship,aliens,bullets,stats,play_button,mouse_x,mouse_y)

def check_play_button(ai_settings,screen,stats,play_button,ship,aliens,bullets,mouse_x,mouse_y):
    button_clicked=play_button.rect.collidepoint(mouse_x,mouse_y)
    if button_clicked and not stats.game_active:
        pygame.mouse.set_visible(False)
        stats.reset_stats()
        stats.game_active=True
        aliens.empty()
        bullets.empty()
        create_fleet(ai_settings,screen,ship,aliens)
        ship.center_ship()

I want to know why this is happening and how to correct it.Thanks for your help.

You are passing the arguments in the wrong order. They need to be in the same order as in the function definition:

check_play_button(ai_settings,screen,stats,play_button,ship,aliens,bullets,mouse_x,mouse_y)

The error occurs because you pass aliens, which is obviously a sprite group, as the fourth argument. Then in the check_play_button function this aliens group gets assigned to the local variable play_button and since it has no rect attribute, Python raises the AttributeError.
