打印出来了，但是错误： “'播放器'对象不支持索引”弹出。什么是对象不支持索引错误？

当我点击按钮时，椭圆实际上并没有移动。使用tkinter Button，我可以调用该方法，对吗？

但是通过这样做，如果我想做例如，点击按钮，结果椭圆移动到不同的位置，我该如何实现？因为上面的代码，只要点击按钮，椭圆就不会移动。

感谢。由于我对python和编程很陌生，所以任何帮助都会如此感激。

Answer 1

索引是指对[n]后缀的对象，其中n为int。以下是重现该消息的方法。

>>> class C: pass

>>> C()[1]
Traceback (most recent call last):
  File "<pyshell#21>", line 1, in <module>
    C()[1]
TypeError: 'C' object does not support indexing

错误消息上方的文件条目会告诉您给出错误的行号和表达式。代码中的某个位置，如您未向我们展示的回溯所示，您有x [n]，其中x是您定义的Player类的实例。

对象是可订阅的，当且仅当它具有__getitem__方法时Player没有且不应该有。
