有人可以帮我解决Python 3.7索引超出范围错误的问题吗？ （我到处都看过）

Question

评论中的答案---谢谢！ 代码粘贴在下面。这是典型的“ 一次关闭”错误，但我无法弄清楚在哪里，原因或方式。诚然，就数组和索引而言，我实在很垃圾。如果有人可以帮我解决这个问题，我将不胜感激。

所以，我遇到的第一个错误是相同的，但它的目标是arrow数组。您可以在下面的代码中看到我的评论，这些代码在哪里进行了更改以及如何进行了更改。现在，它进入下一个数组，这是从其他两个数组创建的 ndnumpy 数组，并且像我第一次一样，它不允许我“附加”它来修复它。抛出属性错误，表示ndnumpy数组无法添加。

想补充一点，动画将打开并运行一会儿，然后停止并抛出错误。因此，从技术上讲，它有效，只是总是以错误结尾。

真的不需要if循环，它运行完全相同或完全没有......

这是Python IDLE引发的错误：
