There are a number of important differences:

<ol>
<li>Interoperability with other .NET languages. You can use other .NET libraries from an IronPython application, or use IronPython from a C# application, for example. This interoperability is increasing, with a movement toward greater support for dynamic types in .NET 4.0. For a lot of detail on this, see <a href="http://channel9.msdn.com/pdc2008/TL10/" rel="noreferrer">these</a> <a href="http://channel9.msdn.com/pdc2008/TL16/" rel="noreferrer">two</a> presentations at PDC 2008.</li>
<li>Better concurrency/multi-core support, due to lack of a GIL. (Note that the GIL doesn't inhibit threading on a single-core machine---it only limits performance on multi-core machines.)</li>
<li>Limited ability to consume Python C extensions. The <a href="http://code.google.com/p/ironclad/" rel="noreferrer">Ironclad</a> project is making significant strides toward improving this---they've nearly gotten <a href="http://numpy.scipy.org/" rel="noreferrer">Numpy</a> working!</li>
<li>Less cross-platform support; basically, you've got the CLR and <a href="http://www.mono-project.com/Main_Page" rel="noreferrer">Mono</a>. Mono is impressive, though, and runs on many platforms---and they've got an implementation of Silverlight, called <a href="http://www.mono-project.com/Moonlight" rel="noreferrer">Moonlight</a>.</li>
<li>Reports of improved performance, although I have not looked into this carefully.</li>
<li>Feature lag: since CPython is the reference Python implementation, it has the "latest and greatest" Python features, whereas IronPython necessarily lags behind. Many people do not find this to be a problem.</li>
</ol>

blocks|key|4456098|text|在编写代码的方式上有一些细微的区别，但最大的区别在于可用的库。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4456099|有了IronPython，您就拥有了所有可用的.Net库，但代价是一些“普通”的python库，我认为这些库还没有移植到.Net+VM中。|4456100|基本上，您应该期望语法和习惯用法是相同的，但是如果您尝试将为IronPython编写的脚本提供给“常规”Python解释器，它将不会运行。相反的方式可能更有可能，但我认为你也会发现不同之处。|4456101|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|$]]

There are some subtle differences in how you write your code, but the biggest difference is in the libraries you have available.

With IronPython, you have all the .Net libraries available, but at the expense of some of the "normal" python libraries that haven't been ported to the .Net VM I think.

Basically, you should expect the syntax and the idioms to be the same, but a script written for IronPython wont run if you try giving it to the "regular" Python interpreter. The other way around is probably more likely, but there too you will find differences I think.

blocks|key|390950|text|嗯，它通常更快。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|390951|不能使用模块，并且只有库的一个子集。|390952|Here's+a+list+of+differences.|offset|length|390953|entityMap|0|LINK|mutability|MUTABLE|url|http://www.codeplex.com/IronPython/Wiki/View.aspx?title=Differences^0|0|0|0|T|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@$F|S|G|T|1|U]]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

Well, it's generally faster.

Can't use modules, and only has a subset of the library.

blocks|key|1063049|text|请参阅博客文章IronPython+is+a+one-way+gate。它总结了我通过在StackOverflow上提问而学到的一些关于IronPython的东西。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1063050|entityMap|0|LINK|mutability|MUTABLE|url|http://www.johndcook.com/blog/2009/02/26/ironpython-is-a-one-way-gate/^0|7|S|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]]]]

See the blog post <a href="http://www.johndcook.com/blog/2009/02/26/ironpython-is-a-one-way-gate/" rel="nofollow noreferrer">IronPython is a one-way gate</a>. It summarizes some things I've learned about IronPython from asking questions on StackOverflow.

blocks|key|391094|text|Python就是Python，唯一的区别是IronPython被设计为在.NET框架上运行，因此可以互操作和使用用其他.NET语言编写的.NET程序集。因此，如果你的平台是Windows，而且你也使用.NET，或者你的公司使用IronPython，那么你应该考虑使用Windows。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|391095|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|$]]

Python is Python, the only difference is that IronPython was designed to run on the CLR (.NET Framework), and as such, can inter-operate and consume .NET assemblies written in other .NET languages. So if your platform is Windows and you also use .NET or your company does then should consider IronPython.

blocks|key|391144|text|IronPython的优点之一是，与CPython不同，IronPython不使用全局解释器锁，因此使线程更有效。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|391145|在标准的Python实现中，线程在每次对象访问时获取GIL。这限制了并行执行，如果您希望充分利用多个CPU，这一点尤其重要。|391146|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|$]]

One of the pros of IronPython is that, unlike CPython, IronPython doesn't use the Global Interpreter Lock, thus making threading more effective. 

In the standard Python implementation, threads grab the GIL on each object access. This limits parallel execution, which matters especially if you expect to fully utilize multiple CPUs.

blocks|key|4456308|text|支持:如果安装了SilverLight，则可以运行IronPython+in+a+browser。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4456309|entityMap|0|LINK|mutability|MUTABLE|url|http://www.codeplex.com/sdlsdk^0|P|N|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]]]]

Pro: You can run <a href="http://www.codeplex.com/sdlsdk" rel="nofollow noreferrer">IronPython in a browser</a> if SilverLight is installed.

blocks|key|391047|text|它还取决于您是否希望您的代码在Linux上工作。不知道IronPython是否能在windows平台之外的任何平台上运行。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|391048|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|$]]

It also depends on whether you want your code to work on Linux. Dunno if IronPython will work on anything beside windows platforms.

How does IronPython stack up to the default Windows implementation of Python from python.org? If I am learning Python, will I be learning a subtley different language with IronPython, and what libraries would I be doing without?

Are there, alternatively, any pros to IronPython (not including .NET IL compiled classes) that would make it more attractive an option?

IronPython如何与python.org的默认Windows实现Python相媲美？如果我在学习Python，我会用IronPython学习一门微妙的不同的语言吗?没有什么库我会做什么？或者，IronPython (不包括.NET IL编译类)有什么优点可以使其更具吸引力吗？
