当我尝试打印QtableWidget的索引时，会出现奇怪的输出？

Question

背景信息

我创建了一个名为自我表格对象我很难从中找到信息。你知道吗

现在我正在尝试选择给定整数的对应行，但是当我这样做并尝试打印我的行时，它将返回none。你知道吗

这让我相信我引用对象的方式是不正确的。你知道吗

所以我试着访问QtableWidget的垂直索引，看看是否可以得到任何输出，但是当我这样做时，它会返回以下结果。。。你知道吗

<PyQt5.QtCore.QModelIndex object at 0x00000000047BC5F8>

问题

有人能解释为什么输出是这种格式，以及如何将其转换为实际的索引列表吗？你知道吗

如果有人能帮我选择QtableWidget的行，那也会很有帮助。你知道吗
