如何自动格式化一些 Python 代码以正确格式化?
问题描述
我有一些现有的代码格式不一致——有时两个空格用于缩进，有时四个空格等等.代码本身是正确且经过充分测试的，但格式很糟糕.
I have some existing code which isn't formatted consistently -- sometimes two spaces are used for indent, sometimes four, and so on. The code itself is correct and well-tested, but the formatting is awful.
网上有没有一个地方可以让我简单地粘贴一段 Python 代码并自动为我缩进/格式化?或者，是否有一个 X 以便我可以执行类似 X --input=*.py 之类的操作并让它用格式化版本覆盖每个文件?
Is there a place online where I can simply paste a snippet of Python code and have it be indented/formatted automatically for me? Alternatively, is there an X such that I can do something like X --input=*.py and have it overwrite each file with a formatted version?
解决方案
现在，我会推荐 autopep8，因为它不仅可以纠正缩进问题，而且(由您自行决定)使代码符合许多其他 PEP8 准则.
Nowadays, I would recommend autopep8, since it not only corrects indentation problems but also (at your discretion) makes code conform to many other PEP8 guidelines.
使用 reindent.py.它应该与 Python 的标准发行版一起提供，但在 Ubuntu 上您需要安装 python2.6-examples 包.
Use reindent.py. It should come with the standard distribution of Python, though on Ubuntu you need to install the python2.6-examples package.
您也可以在 网络上找到它.
You can also find it on the web.
