当持有两个整数骰子时，Python偶然出现列表索引错误

当我选择持有两个骰子时，它并不总是遵循脚本。它发生在大约第50行。有时它甚至不打印列表。 （作为旁注——如果有人能简化代码，我们将不胜感激。） 任何人都能为这个问题提供解决方案和理由吗。 （脚本如下）

随机

模块提供的内容

下面是生成一轮Yatzy的建议简单解决方案

注意：该解决方案使用格式化字符串文本，因此需要Python3.6或更高版本

你拿两个骰子是什么意思？我刚刚运行了you程序，当我不断按enter键时，它打印了一个包含5个随机数的列表。该程序代表一个yahtzee游戏：你掷5次骰子，然后你就可以拿骰子了。不幸的是，我还没来得及继续，错误就来了。很明显，你可以持有任意数量的五个骰子，但我只抽出时间对持有的两个骰子的结果进行编码。目前你只能掷一次。那么，在你决定要持有多少骰子之后，会发生什么呢？非常感谢！这回答了我所有的问题，并在足够简单的代码理解！
