python是一个比较活泼的语言，它可以很快速、很方便地实现很多有意思的东西。

最近，学习了一下如何使用python制作一个简单的音乐播放器，整体的效果如下图所示。

# 所需要的导入的库 #

*  tkinter
 *  os
 *  time
 *  threading
 *  pygame

如果没有安装这个库，简单粗暴的

pip install + 库

例如，我没有安装过pygame这个库，

#  准备工作 #

下载音乐，喜欢的歌曲，选择mp3格式

这里，给大家提供一个mp3格式下载的网址，如果大家有其他合适的网址也可以的。

运行程序之后，可以选择“添加音乐”，然后选择本地的文件夹，用于选择需要播放的音乐。

在音乐列表中选择需要播放的音乐，然后就是出现正在播放的音乐。

大概效果就是这样的，之后还可以继续学习，将它改进成为

*  展示正在播放歌曲的歌词
 *  首页的图片可以自动轮番播放
 *  播放音乐mv
