Question

愿意开发一种媒体播放器，当播放一首歌曲时会显示“歌词”，吉他和钢琴代码，但不知道如何开始。我从下面的代码开始，当第一次按下add_play_list按钮时，这给了我“ filedialog not defined”错误，在第二次运行时该错误消失了。代码可以播放文件夹中的歌曲，但是直到播放完所有歌曲后，根帧窗口才“无响应”。我该如何解决这些问题？如何在标签中添加歌词和吉他代码？您的指导会有所帮助。谢谢。

def playaudio(event):

        pygame.mixer.music.load

       while pygame.mixer.music.get_busy():
           pygame.time.Clock().tick(100)

root.mainloop()

根帧在tkinter没有响应
