`Total1` 变量与 `DealerTotal` 变量具有相同的输出，但它们应该不同时

Question

这是我修改后的二十一点。

我还是 Python 新手，所以这个程序中缺少格式和严重的规则修改，但我不明白的是，如果你要运行这个程序，为什么 Total1 的输出与 @ 相同987654322@.

在第 1 阶段，如果您只是通过并确认您通过了，那么一切都会顺利进行。您有自己的总数，即Card1 和Card2 的总和，庄家有自己的总数（我作弊并让他击中3 次）：Card1、Card2、Card3 .所以PHASE 1 一切正常。

但是当我输入PHASE 2 时，执行相同的过程（通过和确认）会使Total1 和DealerTotal 输出相同。

为什么PHASE 1 中的DealerTotal 可以工作，而PHASE 2 中的DealerTotal 即使代码相同也不行？

Answer 1

这听起来可能很愚蠢，但 Total1 与 DealerTotal 具有相同值的原因是 Total1 与 DealerTotal 具有相同的值。

您在程序开始时分配变量，然后再也不碰它们。 Total1 是Total1 = Total + Cards[Card3]。总数为Total = Cards[Card1] + Cards[Card2]。所以，Total1 等价于：Cards[Card1] + Cards[Card2] + Cards[Card3]。

现在让我们看看 DealerTotal：DealerTotal = Cards[Card1] + Cards[Card2] + Cards[Card3]。似曾相识？

这不会在第 1 阶段发生，因为您使用 Total 进行比较，而不是 Total1

Answer 2

这是因为你写的逻辑。

Total = Cards[Card1] + Cards[Card2]
Total1 = Total + Cards[Card3]

替换 Total 的值

Total1 = Cards[Card1] + Cards[Card2] + Cards[Card3]

和

DealerTotal = Cards[Card1] + Cards[Card2] + Cards[Card3]

正如您可能看到的，DealerTotal = Total1，这就是它们相同的原因。
