Python 3.x 21点游戏不起作用

在代码停止之前，我不明白它为什么会这样做。它给出了一个你想打还是站的循环，直到它突然停止并在我不打的情况下突然添加另一张卡。问题是“drawPlayerCard（）”调用“drawComputerHand（）”而“drawComputerHand（）”调用“hitStand（）”

说明：

“drawPlayerHand（）”中的第一个问题：

如果len（playerHand）<2：
drawPlayerCard（）
drawComputerHand（）

如果if语句为true，则第二次执行“drawPlayerHand（）。这意味着“drawComputerHand（）”也会执行2次

在“drawComputerHand（）”中也有同样的问题：

如果len（计算机手）<2：
drawComputerHand（）
hitStand（）

---

你自己去修吧。如果您无法修复它，我可以发布更多的代码。

谢谢您，我在drawComputerHand（）和HitStand（）之前添加了一条else语句，这样就可以了。非常感谢你，我没发现问题所在。
