利用Python制作自已的动态屏保

我的环境

win10

python3.X

pycharm

1.编写自己的屏保程序

注意：屏保程序打开就是全屏，可自动循环播放

我的样子如图

1、代码准备

2、编译

1）新建一个虚拟环境安装pygame，pyinstaller两个库

2）使用pyinstaller打包

说明一下，pyinstaller打包，会加载环境里的全部内容，所以需要单独新建环境，这样在dist生成的exe文件会比较小。

pyinstaller 参数和使用说明可以参考：使用Pyinstaller打包exe文件详细图文教程

不用看.spec文件格式，用不到。

3）生成结果

说明：运行程序是没有窗口图标和声音的，需要dist中放一个bfa.mp3.这个是在465行。可以修改成自己的内容。

2.有了可运行程序，使用RAR压缩工具将资源和程序打包成独立可执行exe

1）将声音，图标，python打包生成的exe 打成一个rar

2）打开 dist.rar ，工具拦选择“自解压格式”

完成以上配置后选确定，两次。这时在目录下会生成 dist.exe。这时可以运行查下一下效果。

3.将dist.exe配置成系统屏幕保护

1）将dist.exe 修改成 dist.scr 复制到 C:\Windows目录下双击运行

2）回到电脑桌面，鼠标右击，选择个性化打开如下图：
