# ⭐将“ ”中的路径改为您的音乐所在文件夹的路径     代码只需要改这个
folder_path = "D:\CloudMusic\铜钟\8-11"  # 这是作者的绝对路径。     推荐绝对路径，相对路径也行~


# 操作提示：
"""
⭐音乐命名规则：歌手 + " - " + 歌名
            ⭐中间这必须是 空格+“-”+空格

一、键盘操作：（不是很灵敏，不推荐）
    1.长按空格输入本地歌曲编号⭐
    2.按下←键播放上一首
    3.按下→键播放下一首
二、鼠标操作：（比较灵敏）
    1.点击屏幕左半区/滚轮上滑→上一首歌
    2.点击屏幕右半区/滚轮下滑→下一首歌
