为什么Python pep-8强烈建议在制表符上使用空格来缩进? [英] Why does Python pep-8 strongly recommend spaces over tabs for indentation?
问题描述
我在Stack Overflow和 PEP 8 上看到建议是仅在Python程序中使用空格用于缩进.我能理解需要保持一致的缩进的感觉，而且我感到很痛苦.
I see on Stack Overflow and PEP 8 that the recommendation is to use spaces only for indentation in Python programs. I can understand the need for consistent indentation and I have felt that pain.
是否存在首选空格的根本原因?我本以为使用选项卡要容易得多.
Is there an underlying reason for spaces to be preferred? I would have thought that tabs were far easier to work with.
推荐答案
The answer was given right there in the PEP [ed: this passage has been edited out in 2013]. I quote:
最流行的缩进Python的方法是仅使用空格.
The most popular way of indenting Python is with spaces only.
您还需要什么其他根本原因?
What other underlying reason do you need?
直言不讳:如第一段所述，还要考虑PEP的范围:
To put it less bluntly: Consider also the scope of the PEP as stated in the very first paragraph:
该文档给出了Python代码的编码约定，该Python代码包含主要Python发行版中的标准库.
This document gives coding conventions for the Python code comprising the standard library in the main Python distribution.
目的是使在正式python发行版中提供的所有代码保持一致的格式(我希望我们可以同意这是普遍适用的好东西™).
The intention is to make all code that goes in the official python distribution consistently formatted (I hope we can agree that this is universally a Good Thing™).
由于对于单个程序员来说，空格和制表符之间的决定是a)确实是个问题，并且b)可以通过技术手段(编辑，转换脚本等)轻松解决，因此有一种清晰的方法可以结束所有讨论:选择一个.
Since the decision between spaces and tabs for an individual programmer is a) really a matter of taste and b) easily dealt with by technical means (editors, conversion scripts, etc.), there is a clear way to end all discussion: choose one.
Guido是唯一的选择.他甚至不必给出理由，但他仍然通过引用经验数据来做到这一点.
Guido was the one to choose. He didn't even have to give a reason, but he still did by referring to empirical data.
出于所有其他目的，您可以将此PEP作为建议，也可以忽略它-您的选择，团队的选择或领导者的选择.
For all other purposes you can either take this PEP as a recommendation, or you can ignore it -- your choice, or your team's, or your team leaders.
但是，如果我能给您一个建议:请不要混合使用它们;-) [ed:不再将制表符和空格混用.]
But if I may give you one advice: don't mix'em ;-) [ed: Mixing tabs and spaces is no longer an option.]
