Python for Windows 3.3

3.3.2150

常常被拿来跟Java、Perl等语言相比较的一个物件导向的Script程序语言，与Java一样使用具有跨平台移植特性Bytecode，语法清晰，易学易用，可与其他语言混合使用，有不少专业的人士预测Python是继Java之后的明日之星。程序语言的特性是很难用叁言两语说明的，但是了解Python的人，快来更新最新的版本吧，同时Python的官方网站有很多的文件可供为学习的参考，值得一再造访。

Python 3.2.1 was released on July 10th, 2011.

Python 3.2 is a continuation of the efforts to improve and stabilize the Python 3.x line. Since the final release of Python 2.7, the 2.x line will only receive bugfixes, and new features are developed for 3.x only.

Since PEP 3003, the Moratorium on Language Changes, is in effect, there are no changes in Python's syntax and only few changes to built-in types in Python 3.2. Development efforts concentrated on the standard library and support for porting code to Python 3. Highlights are:

numerous improvements to the unittest module
PEP 3147, support for .pyc repository directories
PEP 3149, support for version tagged dynamic libraries
PEP 3148, a new futures library for concurrent programming
PEP 384, a stable ABI for extension modules
PEP 391, dictionary-based logging configuration
an overhauled GIL implementation that reduces contention
an extended email package that handles bytes messages
a much improved ssl module with support for SSL contexts and certificate hostname matching
a sysconfig module to access configuration information
additions to the shutil module, among them archive file support
many enhancements to configparser, among them mapping protocol support
improvements to pdb, the Python debugger
countless fixes regarding bytes/string issues; among them full support for a bytes environment (filenames, environment variables)
many consistency and behavior fixes for numeric operations
