**实现步骤：**

①下载64位对应`python`版本的`pygame`：`pygame-1.9.6-cp38-cp38-win_amd64.whl`

② 更新`pip`：`python -m pip install --upgrade pip`

③ 安装`pygame`：`pip install pygame-1.9.6-cp38-cp38-win_amd64.whl`

④ 实现代码如下：

import sys  # 导入系统模块
    import random  # 随机数模块
    import pygame  # 导入pygame模块
    import pygame.locals  # 导入pygame本地策略
    
    ICO_PATH = "images/app.ico"  # APP_ICO
    APP_NAME = "飞机大战V1.0"  # APP_NAME
    Enemy_IMGS = ("images/enemy1.png", "images/enemy2.png")  # ENEMY_IMGS
    
    
    # TODO 定义一个公共类
    class Model:
        window = None  # 主窗体window对象
    
        # 初始化函数
        def __init__(self, img_path, x, y):
            self.img = pygame.image.load(img_path)
            self.x = x
            self.y = y
    
        # 将图片填充到背景中
        def display(self):

    # TODO 背景
    class Background(Model):

        def move(self):
            if self.y <= Game.WINDOW_HEIGHT:
