我一直在努力完成该项目的上课时间，除对获胜百分比进行排序外，我已经完成了所有工作。不幸的是，我原计划在学习这一部分的同一天参加CCNA考试，但我似乎无法理解这一概念。我的教授使用了一种将每个元素与最初设置为“ 0”的“ lowIndex”变量进行比较的方法。我似乎无法从他的示例中将其实现到问题中，但是似乎可以通过python的sort方法来完成。我的问题是让它真正起作用并正常运行。下面是我的“稳定代码”，但是我还有一个测试文件，我一直在其中工作，我在这里创建了一个新函数来进行排序，但是我也一无所获。本质上，我希望它按从高到低的顺序排序，但是我认为我需要将它从for循环中删除，但是当我这样做时，我会遇到更多问题，这使我不得不更多地屠杀我的代码。再次，我觉得现在已经成功（我相信）创建了一个percent []数组，.sort应该可以正常工作，实际上我在实现它时遇到了一个问题。我需要对其进行正确排序，以便当它在“ viewRecords”中显示时，将按从高到低的顺序列出。任何帮助将不胜感激。
