此文转载自：https://blog.csdn.net/qq_36079986/article/details/110395731

记得刚学python那会，作过一个飞机大战小项目，这个项目非常经典，可以帮助初学者提高动手能力，今天把它分享出来

一、项目介绍
二、项目实现
- １.首先安装库
- ２.主要python代码
三、说明：代码功能都在注释里面，我就不做过多解释了；与本项目有关的图片数据我传到资源里面了，大家可以免费下载，我把代码和数据都打包到一起了，大家下载下来导入库就可以直接一些了。
四、完整版代码及数据下载地址（下载就能用）

一、项目介绍

先放几张图片

二、项目实现

１.首先安装库

pip install pygame

２.主要python代码

import pygame
from pygame.locals import *
import random
