Python 3.1.1 RC发布

wyg1258

Python是一门跨平台的脚本语言,Python规定了一个Python语法规则,实现了Python语法的解释程序就成为了Python的解释器,我 们用的比较多的是C版本的Python,也就是使用C语言实现的Python解释器,除此之外还有使用Java实现的Jython和使用.NET实现的 IronPython,这些实现可以使Python用户充分利用己有的Java及.NET资源.
The Python 3.1.1 release candidate was released on August 13th, 2009.
Python 3.1 is a continuation of the work started by Python 3.0, the new backwards-incompatible series of Python. Improvements in this release include:

• An ordered dictionary type
  
• Various optimizations to the int type
  
• New unittest features including test skipping and new assert methods.
  
• A much faster io module
  
• Tile support for Tkinter
  
• A pure Python reference implementation of the import statement
  
• New syntax for nested with statements
