我收到这个错误..
追溯（最近的最后一次呼叫）：
文件chomp.py，第110行，在类Wall（Immovable）中：
文件chomp.py ，第124行，在邻居邻居的墙上：
名称错误：未定义名称邻居
我花了很多时间仍然找不到什么问题，需要一些帮助
未完成的调用 Circle（）可能是尝试正确格式化代码时出错。请检查您是否发布了您实际运行的代码，并且追溯是您实际获得的代码（有一些失踪！）。
报告的错误在（可怕格式）的追溯中，邻居在邻居中的邻居行中未定义：。编译器绝对没有办法通过干预的方式来解决这个问题。
（x，y）= self.place
neighbors = [（x + 1，y），（x-1，y）]
没有其他类型的错误。
注意：上面是针对另外一个我正在回答的问题。留下它，以便您知道您对该问题的建议是错误的。
我怀疑在您的第一个问题（ width 未在行 for x in range（width）：），您没有修复所有的缩进错误，邻居中的邻居的Q2和Q3行 code>应该在其显示的右侧移动4个空格。
您的源文件中有任何选项卡吗？如果是这样，请删除它们。如果您不确定如何保持标签免费，请单独提出问题，说出什么编辑器和什么操作系统以及熟悉该组合的人可以帮助您。 >
如何在源文件中查找标签：

I got this error..
Traceback (most recent call last):
File "chomp.py", line 110, in class Wall(Immovable):
File "chomp.py", line 124, in Wall for neighbor in neighbors:
NameError: name 'neighbors' is not defined
I spent lot of time still can't find what's wrong, need some help
The unfinished call to Circle() is probably the result of an error trying to format the code properly. Please check that you post the code that you actually ran, and the traceback is the one that you actually got (there's some of this one missing!).
The error reported in the (horribly formatted) traceback is that neighbors is undefined in the line for neighbor in neighbors:. There is absolutely no way the compiler would munch its way through the intervening lines
(x, y) = self.place
neighbors = [ (x+1, y), (x-1, y)]
without some other kind of error.
Note: the above was in response to another question that was closed as I was answering it. I am leaving it in so that you know that the advice that you got for that question was wrong.
I suspect that after your FIRST question (width not defined in line for x in range( width ):), you didn't fix all your indentation errors, and the Q2 and Q3 line for neighbor in neighbors: should be shifted 4 spaces to the right of where it appears to be.
Do you have any tabs in your source files? If so, get rid of them. If you are not sure about how to stay tab-free, ask a separate question, say what editor and what OS and maybe someone familiar with that combination can help you.
How to find tabs in your source file:
C:\junk>\python27\python -c "print[x for x in enumerate(open('sometabs.py'),1)if'\t'in x[1]]"
[(1, 'foo\tbar\n'), (3, '\t\toof\n')]
