python实现的音乐播放器

音乐播放器，原来写过一个简陋的例子，可见

那个不能拖动播放进度条上的滑块到新的位置播放。下面介绍的可以。

简单实用的音乐播放器

这个简单实用的音乐播放器，运行界面：

需要安装，PyQt6这个第三方库。

专业级别的音乐播放器

下面这个音乐播放器，源码来源于网络，适当修改，转载记录于此。

需要安装PyQt6、python-vlc、mutagen 这3个第三方库。

还需要安装 VLC 播放器（python-vlc 是 VLC 的 Python 绑定，需依赖系统安装的 VLC），访问 VLC 官网Official download of VLC media player, the best Open Source player - VideoLAN ，下载并安装对应系统的版本。否则 程序运行时提示 vlc.dll not found。
