python如何实现可下载音乐的音乐播放器

小编给大家分享一下python如何实现可下载音乐的音乐播放器，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

1.确定页面

SongSheet------ 显示歌单MusicCtrl ------显示音乐一些控件(播放,跳转,音量调节)SearchWindows ------搜索栏(搜索歌曲默认显示20条,可下载)

songSheet.py

classSongSheet(tkinter.Frame):
def__init__(self,master):
self.frame=tkinter.Frame(master,height=230,width=300,bd=1,
bg="SkyBlue")
self.frame.place(x=0,y=0)
self.filePath="C:\Musics"
self.music=""#点击歌曲获得更新的路径
self.count=0#计数,共多少歌曲

defrun(self):
#搜索按钮
searchBtn=tkinter.Button(self.frame,text="更新",bg="SkyBlue",
command=self.showSheet,width=10,
height=1)

searchBtn.place(x=0,y=200)

#显示歌单
defshowSheet(self):
self.count=0
musics=os.listdir(self.filePath)
tree=ttk.Treeview(self.frame)
#定义列
tree["columns"]=("song")
#设置列,列还不显示
tree.column("song",width=95)

#设置表头和上面一一对应
tree.heading("song",text="song")

#添加数据往第0行添加
formusicinmusics:
#去除空格
music="".join(music.split(""))
tree.insert("",0,text=self.count,values=(music))
self.count+=1

#鼠标选中一行回调
defselectTree(event):
foritemintree.selection():
item_text=tree.item(item,"values")
self.music="".join(item_text)
#print(self.music)

#选中行
tree.bind('<>',selectTree)
tree.place(width=300,height=200,x=0,y=0)

#添加滚动条
sy=tkinter.Scrollbar(tree)
sy.pack(side=tkinter.RIGHT,fill=tkinter.Y)
sy.config(command=tree.yview)

2.写出音乐控件
