python实现可下载音乐的音乐播放器

本文实例为大家分享了tkinter+pygame+spider实现音乐播放器，供大家参考，具体内容如下

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

import tkinter
import os
from tkinter import ttk
import time

class SongSheet(tkinter.Frame):

         command=self.showSheet, width=10,

 # 显示歌单

  tree = ttk.Treeview(self.frame)
  # 定义列
  tree["columns"] = ("song")
  # 设置列,列还不显示
  tree.column("song", width=95)
