利用Python制作自已的动态屏保
作者:Brickie-liu
这篇文章主要为大家详细介绍了如何利用Python制作自已的动态屏保,文中的示例代码讲解详细,对我们学习Python有一定的帮助,需要的可以参考一下
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:
