Question

我年轻的堂兄不知何故拿到了一本蟒蛇书，一直在努力学习Python。他向我求助。但是我很难做到这一点。

他正在使用IDLE，他报告说他收到了这个错误：

               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.

他给我发了一份他的代码副本，缩进是正确的。由于许多语法错误，它无法运行，但这并不重要。他报告说他使用了Format-＆gt; Untabify Region，但问题并没有解决。

我不能为我的生活弄清楚为什么我可以运行他的python文件，但他不能。有没有人知道这是怎么回事？我很遗憾地目前正坐飞机飞行五个小时，否则我会看到发生了什么事。

他的代码在这里，当我尝试运行它时没有任何缩进错误，所以我怀疑它告诉你任何有用的东西。如果有问题，那么在我拿到它的时候它就会以某种方式被移除。

Answer 1

with open('problem_script.py','r') as f:
    content = f.read()
    print(repr(content))

很有可能他的文件中隐藏着不可见的字符。使用上面的程序将帮助他找到它们。

Answer 2

这可能是Windows / Unix行结束问题。您是否在两个不同的操作系统之间交换python代码？如果是这样，请尝试运行dos2unix或unix2dos，将系统结尾设置为IDLE正在运行的系统上的正确格式。
