Python解释器 发展史

python 运行核心 解释器的发展史：

# 1989年，Guido开始写Python语言的编译器。 # 1991年，第一个Python编译器诞生。它是用C语言实现的，并能够调用C语言的库文件。从一出生，Python已经具有了：类，函数，异常处理，包含表和词典在内的核心数据类型，以及模块为基础的拓展系统。 # Granddaddy of Python web frameworks, Zope 1 was released in 1999 # Python 1.0 - January 1994 增加了 lambda, map, filter and reduce. # Python 2.0 - October 16, 2000，加入了内存回收机制，构成了现在Python语言框架的基础 # Python 2.4 - November 30, 2004, 同年目前最流行的WEB框架Django 诞生 # Python 2.5 - September 19, 2006 # Python 2.6 - October 1, 2008 # Python 2.7 - July 3, 2010 # In November 2014, it was announced that Python 2.7 would be supported until 2020, and reaffirmed that there would be no 2.8 release as users were expected to move to Python 3.4+ as soon as possible # Python 3.0 - December 3, 2008 (这里要解释清楚 为什么08年就出3.0，2010年反而又推出了2.7？是因为3.0不向下兼容2.0，导致大家都拒绝升级3.0，无奈官方只能推出2.7过渡版本) # Python 3.1 - June 27, 2009 # Python 3.2 - February 20, 2011 # Python 3.3 - September 29, 2012 # Python 3.4 - March 16, 2014 # Python 3.5 - September 13, 2015 # Python 3.6 - 2016-12-23 发布python3.6.0版
