1. 程序运行结果

Python实现音乐播放器(爬虫、多线程、进度条、文件)

2.程序实现原理

本音乐播放器GUI方面运用Python的tkinter实现，播放的音乐来自网络爬虫和本电脑已经有的。为了使整个程序运行起来不卡顿，运用多线程[不运用多线程会出现卡顿现象，读者可以看看小编之前的文章，里面有一篇是关于Python实现音乐播放器的，当时效果就是出现卡顿]。

3. GUI布局

说到布局，tkinter提供的有3种，小编使用的是grid布局，这种布局很容易让人理解自己做的一些控件、标签等在整个窗口的位置。

4. 功能介绍

整个音乐播放器的效果就是上述那样。

1. 如果要搜索线上音乐，直接在搜索框里输入歌名，然后按电脑键盘的Enter,然后搜索框下面的列表框里就会给出搜索的结果，如果想听其中的一首，鼠标点击到那一首歌曲那然后双击鼠标左键，即可播放音乐。如果我们想把播放的音乐收藏，直接点击鼠标右键即可;
2. 如果我们想听我的收藏里的歌曲，直接点击我的收藏，然后列表框里的内容就会变成已经收藏的音乐，此时不是双击鼠标左键进行播放，而是选中其中一首，然后点击下面的播放按钮进行播放，如果我们想要歌曲循环播放，点击下面的循环播放即可(注：循环播放只支持收藏的音乐)；
3. 调节音量的大小，使用Scale控件(循环播放前面那个玩意)；
4. 设置按钮可以用来设置歌词的字体颜色、字体大小、字体格式和背景颜色，用的是下拉框，设置之后，保存即可。

5. 代码实现

代码有点多，且涉及到文件读写，就不不把代码一一粘贴出来了，想要的读者直接去资源下载即可。
这是其中一部分。
