**小弟是小白因大作业，在此博文的基础上，我增加了歌曲目录的选择，自动播放，实时显示歌词名称并能实现自动切歌的功能，后续可能会增加一下实时显示动态歌词，歌曲下载等功能。于是写一篇博客记录一下。望大神指教！**

自动播放的关键在于用多线程编程来跳出自动播放在GUI界面设计中死循环！  
废话不多说，代码如下：  
***main\_test.py***

import tkinter
    import os
    from musicTree import TreeWindows
    from lyric import Lyric
    from musicButton import MusicButton
    import sys, time
    from tkinter.filedialog import askdirectory
    
    sys.path.append('/Users/wangrui/PycharmProjects/pythonProject/final homework/music')
    
    win = tkinter.Tk()
    win.title("何猪音乐播放器")
    win.geometry("950x700+300+100")
    
    # path = r"/Users/wangrui/Downloads/test"
    path = askdirectory()
    frameL = tkinter.Frame(win)
    frameL.pack(fill=tkinter.Y, side=tkinter.LEFT)
    
    frameR = tkinter.Frame(win)
    frameR.pack(fill=tkinter.Y, side=tkinter.RIGHT)
    
    treeWin = TreeWindows(frameL, path)
    button = MusicButton(frameR, path)
    win.mainloop()

目录选择的根本在于askdirectory函数。

其中cycle\_play是自动播放函数，在fun5中使用多线程调用了这个函数，使得可以通过外部指令打破自动播放中的for死循环。

先对歌曲目录进行选择～～～～

然后GUI界面如下，有自动播放，上一曲，下一曲，播放，暂停功能。

我们播放一首歌试试～～点击自动播放按钮，音乐就开始播放啦，并且能实时显示歌曲名称和根目录～～

完结，撒花～～以后可能会增加一些歌词动态实时显示，图片作为背景插入循环显示，随机播放等等功能～～  
小弟刚接触python，有什么写得有问题的地方，望大神指教。
