我目前正在尝试制作一个宝岛游戏，其中代码打印出一个10x10（试图让这个首先工作，然后实现其余大小的地图），地图左下角有一个X.然后，用户告诉程序它想要向上，向左，向右和向下移动角色多少个位置然后移动。

它还应该随机隐藏硬币以允许角色获得积分。

目前我无法通过电路板上的X打印电路板。现在它返回错误

Traceback (most recent call last):
  File "*file Root*/Controlled Assessment (1).py", line 91, in <module>
    board10()
  File "*file Root*/Controlled Assessment (1).py", line 17, in board10
    charac[x][y] = 'x'
NameError: name 'x' is not defined

非常感谢任何帮助！

charac[x][y] = 'x'
       ^

当您为列表编制索引时，正如您在此处所做的那样，您应该使用评估为数字的内容。例如，如果您有一个名为lst的变量，其中包含值[1, 2, 3, 4, 5]（包含5个数字的列表），则lst[0]为1，lst[3]为4，等等。除了使用文字编号之外，您还可以使用包含数字的变量，例如foo被定义为2（您可以使用代码语句foo = 2执行），然后lst[foo]是3。这是您在代码中尝试执行的操作，使用x下存储的值来索引列表charac。但是，您实际上从未在x中添加数字，因此Python不知道如何处理它。这就是您收到此错误的原因。

重现此错误的一个非常简单的程序是

lst = [1, 2, 3, 4, 5]
print(lst[x])

修复此程序的一种简单方法是将其更改为以下内容：

lst = [1, 2, 3, 4, 5]
x = 2
print(lst[x])

将来，如果您尝试将程序缩减到可能出现错误的最小示例，就像我刚刚展示的那样，您将很容易找到许多错误。
