Python: 缩进错误

Question

我表弟最近拿到了一本Python书，正在努力学习Python。他找我帮忙，但我有点搞不定。

他在用IDLE这个工具，报告说遇到了一个错误：

               Error: Inconsistent indentation detected!

    1)      Your indentation is outright incorrect (easy to fix), OR
    2)      Your indentation mixes tabs and spaces.

                   To fix case 2, change all tabs to spaces by using Edit->Select All
                   Followed by Format->Untabify Region and specify the number of
                   Columns used by each tab.

他把他的代码发给我看，缩进是正确的。不过代码运行不起来是因为有几个语法错误，但这不是重点。他说他用过“格式->去掉制表符”这个功能，但问题还是没解决。

我真搞不懂为什么我能运行他的Python文件，而他却不行。有没有人知道这是怎么回事？可惜我现在离他有五个小时的飞机距离，不然我可以亲自去看看。

他的代码在这里，我运行的时候没有缩进错误，所以我怀疑这对你们没有什么帮助。如果有问题的话，可能在我拿到代码的时候就已经被修复了。
