Try Emacs. It has good support for indentation needed in Python. Please check this link <a href="http://python.about.com/b/2007/09/24/emacs-tips-for-python-programmers.htm" rel="nofollow noreferrer">http://python.about.com/b/2007/09/24/emacs-tips-for-python-programmers.htm</a>

blocks|key|1309321|text|还有PythonTidy+(因为你说你喜欢HTML+Tidy)。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1309322|不过，它可以做的不仅仅是清理标签。如果你喜欢这种类型的东西，它值得一看。|1309323|entityMap|0|LINK|mutability|MUTABLE|url|http://pypi.python.org/pypi/PythonTidy/1.16^0|2|A|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

There is also <a href="http://pypi.python.org/pypi/PythonTidy/1.16" rel="nofollow noreferrer">PythonTidy</a> (since you said you like HTML Tidy).

It can do a lot more than just clean up tabs though. If you like that type of thing, it's worth a look.

blocks|key|1524427|text|如果你很懒(像我一样)，你也可以下载一个试用版的Wingware+Python+IDE，它有一个自动修复工具来修复混乱的缩进。它工作得很好。http://www.wingware.com/|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1524428|entityMap|0|LINK|mutability|MUTABLE|url|http://www.wingware.com/^0|1Y|O|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

If you're lazy (like me), you can also download a trial version of Wingware Python IDE, which has an auto-fix tool for messed up indentation. It works pretty well.

blocks|key|1524477|text|对于这个问题我有一个简单的解决方案。你可以先输入":retab“，然后输入":retab!"，然后一切就好了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1524478|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I have a simple solution for this problem. You can first type ":retab" and then ":retab!", then everything would be fine

blocks|key|1524523|text|在大多数类UNIX系统上，您还可以运行：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1524524|expand+-t4+oldfilename.py+>+newfilename.py|code-block|syntax|javascript|1524525|在命令行中，如果要将制表符替换为除4以外的空格，请更改数字。您可以轻松地编写一个shell脚本，一次使用一组文件执行此操作，并保留原始文件名。|1524526|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

On most UNIX-like systems, you can also run:

<pre><code>expand -t4 oldfilename.py &gt; newfilename.py
</code></pre>

from the command line, changing the number if you want to replace tabs with a number of spaces other than 4. You can easily write a shell script to do this with a bunch of files at once, retaining the original file names.

blocks|key|1524697|text|由于缺少一些模块，所以reindent脚本对我不起作用。无论如何，我发现这个sed命令非常适合我：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1524698|sed+-r+'s/%5E([++]*)([%5E+])/\1\1\2/'+file.py|code-block|syntax|javascript|1524699|entityMap^0|12|3|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

The reindent script did not work for me, due to some missing module. Anyway, I found this <code>sed</code> command which does the job perfect for me:

<pre><code>sed -r 's/^([ ]*)([^ ])/\1\1\2/' file.py
</code></pre>

blocks|key|1309763|text|谷歌还有一个很棒的项目，叫做YAPF|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1309764|它可以自动重新格式化整个项目或检查项目是否有正确的缩进/格式。我在一个商业项目中使用了它，并且我推荐它。|1309765|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/google/yapf^0|E|4|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

There is also a Google awesome project called <a href="https://github.com/google/yapf" rel="nofollow noreferrer">YAPF</a>
It can automatically reformat the whole project or check if the project has correct indentation/format. I used that in a commercial project and I recommend that.

I have some Python code that have inconsistent indentation. There is a lot of mixture of tabs and spaces to make the matter even worse, and even space indentation is not preserved.

The code works as expected, but it's difficult to maintain.

How can I fix the indentation (like <a href="https://en.wikipedia.org/wiki/HTML_Tidy" rel="noreferrer">HTML Tidy</a>, but for Python) without breaking the code?

How to fix Python indentation

Python

我有一些缩进不一致的Python代码。有许多制表符和空格的混合使事情变得更糟，甚至空格缩进都没有保留。代码按预期工作，但很难维护。如何在不破坏代码的情况下修复缩进(类似于，但适用于Python)？
