我试图从经销商手和玩家手中获得总价值，但是我似乎无法得到它，因为变量没有定义。我只是想比较分数，所以我告诉他们是否都击中了二十一点，谁输了或谁赢了
谢谢。

请分享完整的代码，如果没有它将无法帮助您，但我想指出您将'dealers_hand'声明为列表，因此您无法将其比作“dealers_hand == 21” 。你将不得不循环遍历列表的元素，然后对它求和，然后将总和分开。

请参阅以下主文件更新。你有一个方法来检查手的结果。因此，运行该方法，然后相互检查总和以确定胜利者是可行的。
您已尝试检查dealer_hand == 21但是它是一个列表，并且该列表不包含该手的分数。您需要通过get_hand_score（手）传递手来确定结果。获得结果后，您可以计算并确定获胜者。 ：）
