类型错误:'int'对象没有属性'__getitem__'错误。

I have a list to store the X and Y of bullets in my game, and when spacebar is pushed, it adds an x and y to the list, and then it should call both values and draw them. i know i need to delete them after they leave the screen, but atm when i hit space this error pops up

在我的游戏中，我有一个列表来存储子弹的X和Y，当空格键被推时，它将X和Y添加到列表中，然后它应该调用两个值并绘制它们。我知道我需要在他们离开屏幕后删除它们，但是当我点击空格时，这个错误会弹出。

   TypeError:'int' object has no attribute '__getitem__'

here's my code:

这是我的代码:

#start system
import pygame, sys, random
from pygame.locals import*
pygame.init()
fps=50
Clock=pygame.time.Clock()#use fps as system time
#set up a list of STUFF
BLACK = ( 0, 0, 0)
WHITE = ( 255, 255, 255)
GREEN = ( 0, 100, 0)
RED   = ( 100, 0, 0)
YELLOW= (255,255,0)
ORANGE= (255,165,0)
screensizex=800
screensizey=600
bullets=[]
screenarea=pygame.display.set_mode((screensizex,screensizey))
pygame.display.set_caption("space invaders")
player_x=250
# end of variable init, begin main loop!
while 1==1:
    #key roster
    for event in pygame.event.get():
        if event.type==QUIT:
            pygame.quit()
            sys.exit()
        if event.type==KEYDOWN:
            if event.key==K_d and player_x<screensizex-25:
                player_x+=25
            if event.key==K_a:
                player_x-=25
            if event.key==K_SPACE:
                bullets.insert(player_x,665)
    #drawing to screen             
    screenarea.fill(WHITE)
    for bullet in bullets:
        pygame.draw.rect(screenarea,ORANGE,Rect(bullet[0],bullet[1],5,10))
    pygame.draw.rect(screenarea,GREEN,(0,screensizey-100,screensizex,100))
    pygame.draw.rect(screenarea,RED,(player_x,screensizey-125,25,25))
    pygame.display.update()
    Clock.tick(fps)

can you help me out? how do i call both values?

你能帮我吗?我如何调用这两个值?

It looks like you meant to put tuples into your list, so this:

看起来你想把元组放到你的列表里，所以这个:

bullets.insert(player_x,665)

Should be:

应该是:

bullets.append((player_x,665))
