Question

对于有效和无效的代码抱歉

让我先从代码的基本规则开始。袋子存放在床垫下面，每个袋子只能包含硬币。单独地，它们只能包含一种类型的硬币。因此，便士袋不能包含硬币或任何其他硬币，只有便士。

好吧，我在这里的问题是，当我存钱时，无论我存入什么“袋”，硬币自动转到Dime包，我找不到代码中的哪个位置发生。从我的观点来看，代码是有意义的（它对我而言，但不是计算机）。我真的觉得我只需要第二眼看着它。我也不是一个没有真正帮助的python程序员

我找到了你的问题。

让我向您解释我是如何找到您的问题的，所以下次您可以找到它。

我在代码中添加了一行

print("Q")
userMain.qBag.SetCoin(depCoin)

考虑到你的程序尝试做什么，我希望在我尝试添加季度时打印。但它从未打印过，表明在此之前已经发生了一些事情。

接下来我添加了另一行：

depAction = input("Select an option: ")
print("GOT", depAction)

然后我再次运行程序，然后打印出来。

现在我知道问题出在两个打印语句之间。鉴于该程序最终将其添加到角钱中，它使得它看起来像某种程度上我们最终运行了角钱添加代码，即使我输入了q。我查看检查进入角钱部分的代码并查看问题。

我看到了问题，但是为了进行教学练习，我认为你应该自己找到它。
