错误输出

AttributeError: 'member_descriptor' object has no attribute 'put'

我目前有一个MusicPlayer类供我的机器人以我想要的方式播放音乐。我相信我的命令导致了这个问题，但是我不确定。我从未听说过member_descriptor，并且在查找时似乎对这个错误的了解不多。我只想将歌曲添加到队列中并按此顺序播放，如果队列中没有歌曲，则应该播放。

下面是我的班级和指挥部。任何帮助都非常感谢！

Answer 1

类MusicPlayer具有由queue创建的描述符__slots__。在执行MusicPlayer.queue时，您将直接访问该描述符，而不是使用music_player.queue来访问实例的属性。

有时，您需要从类中创建一个MusicPlayer对象，并使用它代替类本身。
