我看了一下tabnanny来检查一个python源文件。 但我没找到任何东西，tabnanny 能够通过编译命令找到无法找到的东西。 或者我错过了什么？ Tabnanny旨在检查缩进 是否有混合标签和空格。具有混合选项卡的文件 和空格_can_编译就好了如果编辑器生成它们的b $ b与编译器一致同意 那些空格的数量一个标签占据。 另一方面，这样的文件很可能会被搞砸几乎无法修复如果有人尝试 在编辑器中编辑它们以不同方式处理标签 来自生成它的那个。 坚持一个或另一个的文件总是 可以正确编辑和编译。 python 建议使用空格，但不是 每个人都同意这个。 大多数现代的Python感知编辑器处理 情况合理，虽然你可能有 来设置参数。 John Roth 最好的问候， - Franz Steinhaeusler

感谢您的解释。 我试过找到： def a（）： - >打印 - > .print 其中point是空格。 tabnanny here抱怨和python编译得很好。 - Franz Steinhaeusler

真的吗？这是一个语法错误（你不能改变缩进nillywilly 在一个块内），而我正在使用的Python肯定会将此标记为错误：

Hi, I looked at tabnanny to check a python source file. But I didn''t find anything, tabnanny is able to find, what couldn''t be found by compile command. Or have I missed something? Tabnanny is intended to check whether indentation has mixed tabs and spaces. Files with mixed tabs and spaces _can_ compile just fine if the editor that produced them agrees with the compiler about the number of spaces that a tab occupies. On the other hand, such files are quite likely to be messed up almost beyond repair if one tries to edit them in an editor that treats tabs differently from the one that produced it. Files that stick to one or the other can always be edited and compiled properly. The python recommendation is to use spaces, but not everyone agrees with this. Most modern Python-aware editors handle the situation reasonably, although you may have to set parameters. John Roth best regards, -- Franz Steinhaeusler

Thanks for your explanation. I tried an found: def a(): ->print ->.print where point is a space. tabnanny here complains and python compile it just fine. -- Franz Steinhaeusler

really? that''s a syntax error (you cannot change indentation nillywilly inside a block), and the Python I''m using surely flags this as an error:
