TypeError: 'Book' object does not support indexing

引用\[1\]中提到，"TypeError: 'dict_keys' object does not support indexing"错误是因为Python 3以后的版本改变了dict.keys的返回值，返回的是dict_keys对象，不支持索引值。\[1\]而引用\[2\]中指出，在Python 3中，dict.values()（以及dict.keys()和dict.items()）返回的是一个视图对象，而不是一个列表。为了解决这个问题，可以将返回的对象强制转换为list对象，如引用\[3\]所示。所以，对于你提到的"TypeError: 'Book' object does not support indexing"错误，可能是因为你在尝试对一个Book对象进行索引操作，而Book对象不支持索引。如果你想对一个对象进行索引操作，你需要确保这个对象是一个可索引的类型，比如列表或字符串。
