Tool to convert python indentation from spaces to tabs?
提问by Corey
I have a some .py files that use spaces for indentation, and I'd like to convert them to tabs.
我有一些使用空格进行缩进的 .py 文件，我想将它们转换为制表符。
I could easily hack together something using regexes, but I can think of several edge cases where this approach could fail. Is there a tool that does this by parsing the file and determining the indentation level the same way the python interpreter does?
我可以使用正则表达式轻松地将某些东西组合在一起，但我可以想到这种方法可能会失败的几种边缘情况。是否有一种工具可以通过解析文件并以与 python 解释器相同的方式确定缩进级别来执行此操作？

If there are not many files to convert, you can open them in vim, and use the :retabcommand.
如果要转换的文件不多，可以在vim 中打开，使用:retab命令。
See the vim documentationfor more information.
有关更多信息，请参阅vim 文档。

Python includes a script for the opposite (tabs to spaces). It's C:\Python24\Tools\Scripts\reindent.pyfor me
Python 包含一个相反的脚本（制表符到空格）。这是C:\Python24\Tools\Scripts\reindent.py给我的

:retab will swap tab with spaces, and :retab! will swap spaces with tab. 1 tab = 4 spaces, 4 spaces = 1 tab, depending on your tab setting.
:retab 将用空格交换制表符，而 :retab! 将与制表符交换空格。1 个制表符 = 4 个空格，4 个空格 = 1 个制表符，具体取决于您的制表符设置。

In emacs, M-x tabifywill convert spaces to tabs where possible. You'll probably want to set the tab-widthvariable appropriately.
在 emacs 中，M-x tabify将尽可能将空格转换为制表符。您可能希望tab-width适当地设置变量。
I don't know if this addresses your concern that spaces be interpreted in the same way as the python interpreter, but you could always load up python-mode and use M-x indent-region.
我不知道这是否解决了您对空格的解释方式与 python 解释器相同的担忧，但您始终可以加载 python-mode 并使用M-x indent-region.
