Question

背景资讯

我创建了一个名为self.TableOBJ的QtableWidget实例，但我无法从中引用信息。

现在我试图选择给定整数的相应行，但是当我这样做并尝试打印我的行时它返回none。

这让我相信我引用的对象是不正确的。

所以我试图访问我的QtableWidget的垂直索引，看看我是否可以获得任何输出，但是当我这样做时它返回以下内容......

<PyQt5.QtCore.QModelIndex object at 0x00000000047BC5F8>

问题

任何人都可以解释为什么输出采用这种格式以及如何将其转换为实际的索引列表？

如果有人能帮助我选择我的QtableWidget那一行也会有所帮助。

问题源于我的班级MainWindow

中的第299行

当我尝试打印我的QtableWidget的索引时，奇怪的输出？
