通过将不同的信息写入该文件

谁说必须打印到循环中的输出文件

您已经在该循环中收集了计数器统计信息（以便在循环后打印）。只需对输出文件执行相同的操作

---

除此之外：阅读有关数组的内容。当您开始使用变量名（如a1、a2等）时，使用数组通常会使此类代码变得更简单。

如果我理解正确，您可能希望在

输出文件.close（）之前包含此代码。

---

我还建议您检查您的代码，通过使用方法减少重复代码，并在必要时调用它们。

假设您尝试为每个双卷输出代码，只需将打印到文件的代码移出while循环，并使其打印蛇眼、二、三等的最终结果。

您是否尝试输出双打或2个骰子的所有组合的掷骰数？只有双打谢谢。我之前尝试过这个，但没有与其他输出紧密相连。
