单击以执行分配给它的代码时，CTRL 不起作用

Question

所以代码可以正常工作，但我不知道发生了什么，所以如果您单击左 CTRL 或右 CTRL，red/yellow 应该会发射子弹，但没有发生。所以我用 print 来检查代码是否会在 red/yellow_bullet 列表中附加一些东西，但它没有，所以是我这边的问题还是代码中的问题？？？请帮忙

代码：

import pygame
import os

from pygame import event #opereting system


WIDTH, HEIGHT = 900, 500 #this is to make the WINDOW
WIN = pygame.display.set_mode((WIDTH, HEIGHT)) 
pygame.display.set_caption("Maisa Ahmed")

BLACK = (0, 0, 0)

boarder = pygame.Rect(WIDTH//2-5, 0, 10, HEIGHT) 
FPS = 60
SPACESHIP_WIDTH , SPACESHIP_HEIGHT = 55,40
velocity = 5
Bullet_velocity = 7
MAX_BULLETS = 5

YELLOW_HITS = pygame.USEREVENT + 1 
RED_HITS = pygame.USEREVENT + 2

#importing images

将 event.type == pygame.K_LCTRL 更改为 event.key == pygame.K_LCTRL，将 event.type == pygame.K_RCTRL 更改为 event.key == pygame.K_RCTRL
