python实战案例：基于Pygame的飞机大战游戏

飞机大战大家都熟悉不过了，相信每个人都有这么一段美好的回忆，作为程序员的我们是不是可以用代码来回忆一下我们失去的青春。python语言博大精深，它目前来说已经很火热了，在学好python的同时还要学会用python，可以使用它来开发一些项目最好不过了。
该游戏在开发之前用到Pygame库，大家一定要记着安装哦！
也可以先通过下列命令查看你是否安装了第三方库Pygame。

pip list

可以看得到我已经安装成功了，如果没有安装，那就请参考文献python在是那种不同软件方式安装第三方库请点击这里

先看看游戏进行时的场面：

展示一下python源代码：

看代码感觉很简单，但是要切实际的运行出来是非常难得，本游戏用到的游戏场景照片均参考自python项目案例开发到入门，大家如果感兴趣可以自己买了多看看哦。
