<ul>
<li>If you're looking to develop software
right now stick with Python 2.6. </li>
<li>If
you're looking to learn the language
and experiment go with Python
3.1.</li>
</ul>

Python 3.1 doesn't have the same library support (yet!) as Python 2.6, so you'll encounter difficulties working with existing software projects. If you're not pressed to produce a working product at this very moment, I'd suggest trying out Python 3.1. And there is no better place to start than <a href="http://diveintopython3.org" rel="nofollow noreferrer">Dive Into Python 3</a>, as has been mentioned by Clint. Good luck!

UPDATE 2011-2-27: I'd say that support for Python 3 is improving constantly and you might want to check and see if your project can't be done with Python 3. There's a website devoted to tracking support for Python 3: <a href="http://getpython3.com/" rel="nofollow noreferrer">http://getpython3.net/</a>

blocks|key|1048508|text|出于以下几个原因，我会选择2.6。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1048509|基于2.6，有更多的材料(书籍、例子等)。有些东西在3.x下可能不起作用，你可以在2.4-6本书上得到一些好的二手交易。|ordered-list-item|1048510|您想要进入的大多数库仍然针对2.6。这将随着时间的推移而改变，但2.6的支持不会在一夜之间消失。差得远呢。Linux发行版(与python有很大关系)至少在一年内都不会继续运行，所以您是安全的！|1048511|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$]]|$1|E|3|F|5|D|7|K|8|@]|9|@]|A|$]]|$1|G|3|-4|5|6|7|L|8|@]|9|@]|A|$]]]|H|$]]

I would go with 2.6 for a couple of reasons.

<ol>
<li>There's so much more material (books, examples, etc) based on 2.6. Some things might not work under 3.x, and you'll be able to get some good second-hand deals on 2.4-6 books.</li>
<li>The majority of libraries you'll want to pull in are still aimed at 2.6. This will change in time, but 2.6 support won't vanish overnight. Far from it. Linux distributions (that have a lot tied into python) aren't planning to move on for at least another year, so you're safe!</li>
</ol>

blocks|key|2573930|text|你真的想继续使用更晚的版本。Python2.6和其馀的2.x版本实际上是为了兼容性。但是，如果您想立即使用像Django这样的框架，这是不正确的，因为它目前与3.x系列不兼容。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2573931|学习Python的小贴士？只要开始使用它，并找到它的在线文档。我觉得这是一种很容易(也很棒)的语言。|2573932|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

You really want to stick with the later version. Python 2.6 and the rest of the 2.x versions that come out are really for compatibility. However, this is not true if you want to use a framework like Django right away because it is incompatible with the 3.x series at the moment.

A tip for learning Python? Just start using it and find online documentation for it. I feel it's an easy (and awesome) language to pick up.

blocks|key|2574055|text|你今天想要2.6美元。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2574056|为什么？因为3.1没有库支持。我们刚刚完成了将setuptools+(名为Distribute)移植到Python+3，因此希望在下一年中对Python+3的库支持将大幅增加，但还没有实现。|2574057|转换也没那么难。这并不是一种全新的语言，就像一些Python评论家说的那样。因此，如果您从Python+3开始，这也不是什么灾难。只是目前很难在Python+3中真正发挥作用。那么就用2.6吧。|2574058|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

You would want to go with 2.6 today.

Why? Because there is no library support for 3.1. We've just finished porting setuptools (under the name Distribute) to Python 3, so hopefully library support for Python 3 will increase dramatically during the next year, but it's not there yet.

And it's not so hard to switch. It's not like it's a whole new language, like some Python critics make it sound like. So if you start with Python 3, it's no disaster either. It's just that it's going to be hard to actually be productive in Python 3 at the moment. So go with 2.6.

blocks|key|1048742|text|从2019年起，除非您正在使用的项目需要Python+2，否则您了解它的唯一原因是了解Python的发展。这可以让您对编程语言开发有一些深入的了解。您可以通过阅读Python3.0发行说明和后续发行说明或阅读一篇关于差异的更现代的文章来了解这些差异。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1048743|但是，此时您不会使用Python+2启动一个新项目，并且试图维护对它的支持已变得适得其反。到那时，在2020年1月1日之后，Python+2将不会得到官方的支持。和许多受欢迎的第三方项目将放弃对它的支持。|1048744|Python+(截至本文撰写之日，11-09年)已有20多岁，Guido和社区在这段时间里学到了很多东西。Guido最初对Python+3的概念是对语言进行修改，主要是为了消除之前版本中出现的疣。

因为维护Python的多个版本对Python开发人员的资源有很大的拖累，而且由于Python+3中包含的语言和库的改进非常重要，所以决定用Python2.7结束Python+2的沿袭。|blockquote|1048745|→PEP+404+-Python2.8未发布计划|1048746|还请参见Python+3什么时候成为新项目的明显选择？|1048747|entityMap|0|LINK|mutability|MUTABLE|url|https://docs.python.org/3.0/whatsnew/3.0.html|1|https://www.python.org/downloads/|2|https://eev.ee/blog/2016/07/31/python-faq-why-should-i-use-python-3/|3|https://www.python.org/dev/peps/pep-0373/#update|4|https://python3statement.org/|5|https://www.python.org/dev/peps/pep-0404/|6|http://python-notes.curiousefficiency.org/en/latest/python3/questions_and_answers.html#when-did-python-3-become-the-obvious-choice-for-new-projects^0|29|D|0|2N|6|1|2W|D|2|0|1D|W|3|2A|B|4|0|0|1|N|5|0|4|N|6|0^^$0|@$1|2|3|4|5|6|7|16|8|@]|9|@$A|17|B|18|1|19]|$A|1A|B|1B|1|1C]|$A|1D|B|1E|1|1F]]|C|$]]|$1|D|3|E|5|6|7|1G|8|@]|9|@$A|1H|B|1I|1|1J]|$A|1K|B|1L|1|1M]]|C|$]]|$1|F|3|G|5|H|7|1N|8|@]|9|@]|C|$]]|$1|I|3|J|5|6|7|1O|8|@]|9|@$A|1P|B|1Q|1|1R]]|C|$]]|$1|K|3|L|5|6|7|1S|8|@]|9|@$A|1T|B|1U|1|1V]]|C|$]]|$1|M|3|-4|5|6|7|1W|8|@]|9|@]|C|$]]]|N|$O|$5|P|Q|R|C|$S|T]]|U|$5|P|Q|R|C|$S|V]]|W|$5|P|Q|R|C|$S|X]]|Y|$5|P|Q|R|C|$S|Z]]|10|$5|P|Q|R|C|$S|11]]|12|$5|P|Q|R|C|$S|13]]|14|$5|P|Q|R|C|$S|15]]]]

As of 2019, unless the project you're working with requires Python 2, the only reason you would learn about it is to understand the evolution of Python. That could give you some insight into programming language development. You can get a grasp on the differences by reading the <a href="https://docs.python.org/3.0/whatsnew/3.0.html" rel="nofollow noreferrer">Python 3.0 release notes</a> and <a href="https://www.python.org/downloads/" rel="nofollow noreferrer">subsequent release notes</a> or reading <a href="https://eev.ee/blog/2016/07/31/python-faq-why-should-i-use-python-3/" rel="nofollow noreferrer">a more modern article about the differences</a>.
However, you wouldn't use Python 2 to start a new project at this point, and trying to maintain support for it has become counterproductive. <a href="https://www.python.org/dev/peps/pep-0373/#update" rel="nofollow noreferrer">Python 2 will receive no official support after January 1, 2020</a>; and <a href="https://python3statement.org/" rel="nofollow noreferrer">many popular third party projects</a> will drop support for it at that point.
<blockquote>
Python is (as of this writing [2011-11-09]) more than 20 years old, and Guido and the community have learned a lot in those intervening years. Guido's original concept for Python 3 was to make changes to the language primarily to remove the warts that had grown in the preceding versions.
...
Because maintaining multiple versions of Python is a significant drag on the resources of the Python developers, and because the improvements to the language and libraries embodied in Python 3 are so important, it was decided to end the Python 2 lineage with Python 2.7.

blocks|key|1055671|text|如果您想使用用C/C%2B%2B编写的现有库和模块，或者使用SWIG，那么您必须使用python2，否则我看不出有什么理由坚持使用python2。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1055672|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|$]]

If you want to use existing libraries and modules written in C/C++ or use SWIG, you'll have to use python2, otherwise I don't really see a reason to stick with python2.

I am about to learn Python and was wondering what is recommended, learning python 2.6 or 3.1? (any tips on learning python is welcomed as well =)

<hr>

edit: Is the difference really big between the two? If I learn python 2 will i have trouble learning python 3?

python 2.6 or python 3.1?
