（1）python应用领域目前Python主要应用领域：
云计算: 云计算最火的语言， 典型应用OpenStack，k8s
WEB开发: 众多优秀的WEB框架，众多大型网站均为Python开发，***, Dropbox, 豆瓣。。。， 典型WEB框架有Django，flask，Tornado
科学运算、人工智能: 典型库NumPy, SciPy, Matplotlib, Enthought librarys,pandas
系统运维: 运维人员必备语言
金融：量化交易，金融分析，在金融工程领域，Python不但在用，且用的最多，而且重要性逐年提高。原因：作为动态语言的Python，语言结构清晰简单，库丰富，成熟稳定，科学计算和统计分析都很牛逼，生产效率远远高于c,c++,java,尤其擅长策略回测
图形GUI: PyQT, WxPython,TkInter
Python在一些公司的应用：
谷歌：Google App Engine 、code.google.com 、Google earth 、谷歌爬虫、Google广告等项目都在大量使用Python开发
CIA: 美国中情局网站就是用Python开发的
NASA: 美国航天局(NASA)大量使用Python进行数据分析和运算
***:世界上最大的视频网站***就是用Python开发的
Dropbox:美国最大的在线云存储网站，全部用Python实现，每天网站处理10亿个文件的上传和下载
Instagram:美国最大的图片分享社交网站，每天超过3千万张照片被分享，全部用python开发
Facebook:大量的基础库均通过Python实现的
Redhat: 世界上最流行的Linux发行版本中的yum包管理工具就是用python开发的
豆瓣: 公司几乎所有的业务均是通过Python开发的
知乎: 国内最大的问答社区，通过Python开发(国外Quora)
春雨医生：国内知名的在线医疗网站是用Python开发的
除上面之外，还有搜狐、金山、腾讯、盛大、网易、百度、阿里、淘宝 、土豆、新浪、果壳等公司都在使用Python完成各种各样的任务。
（2）python的发展史python发展史
1989年，为了打发圣诞节假期，Guido开始写Python语言的编译器。Python这个名字，来自Guido所挚爱的电视剧Monty Python’s Flying Circus。他希望这个新的叫做Python的语言，能符合他的理想：创造一种C和shell之间，功能全面，易学易用，可拓展的语言。
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
