python <tab>自动补全
　　一。这个方法可以修改shell命令行的自动补全
　　1.获取python目录【我使用的是64位ubuntu系统】

• 　　[~$]python
  
• 　　Python 2.7.3 (default, Apr 10 2013, 06:20:15)
  
• 　　[GCC 4.6.3] on linux2
  
• 　　Type "help", "copyright", "credits" or "license" for more information.
  
• 　　>>> import sys
  
• 　　>>> sys.path
  
• 　　['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old',
  
• 　　'/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages',
  
• 　　'/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0',
  
• 　　'/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/ubuntuone-client',
  
• 　　'/usr/lib/python2.7/dist-packages/ubuntuone-control-panel', '/usr/lib/python2.7/dist-packages/ubuntuone-couch',
  
• 　　'/usr/lib/python2.7/dist-packages/ubuntuone-installer', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol']
  
• 　　>>>
  

　　从上面看出python在我电脑上的路径是  /usr/lib/python2.7
　　2.切换至该目录写个startup.py的脚本,脚本目录就是处理python中<tab>事件，脚本内容如下
　　[python]

• 　　#!/usr/bin/python
  
• 　　# python startup file
  
• 
  
• 　　import sys
  
• 　　import readline
  
• 　　import rlcompleter
  
• 　　import atexit
  
• 　　import os
  
• 　　# tab completion
  
• 　　readline.parse_and_bind('tab: complete')
  
• 　　# history file
  
• 　　histfile = os.path.join(os.environ['HOME'], '.pythonhistory')
  
• 　　try:
  
• 　　readline.read_history_file(histfile)
  
• 　　except IOError:
  
• 　　pass
  
• 　　atexit.register(readline.write_history_file, histfile)
  
• 
  
• 　　del os, histfile, readline, rlcompleter
  

　　3.切换至自己主目录
　　[plain]

• 　　[/usr/lib/python2.7$]cd
  
• 　　[~$]vi .bashrc
  

　　4. 增加环境变量
　　[plain]

• 　　#for python
  
• 　　export PYTHONSTARTUP=/usr/lib/python2.7/startup.py
  

　　5.配置环境变量生效
　　[plain]

• 　　[~$]source .bashrc
  

　　PYTHONSTARTUP是什么东西呢？
　　[plain] view plaincopyprint?

• 　　If this is the name of a readable file, the Python commands in that file are executed before the first prompt
  
• 　　is displayed in interactive mode.  The file is executed in the same name space where interactive commands are
  
• 　　executed so that  objects defined  or  imported in it can be used without qualification in the interactive session.
  
• 　　You can also change the prompts sys.ps1 and sys.ps2 in this file.
  

　　二。这个方法能在VIM中自动补全
　　1. 下载插件:
　　下载地址：http://download.csdn.net/detail/loovejava/6284225
　　2.拷贝致相应的目录
　　[plain] view plaincopyprint?

• 　　unzip  pydiction-1.2.1.zip
  
• 　　cp python_pydiction.vim  /usr/share/vim/vim73/ftplugin
  
• 　　mkdir  /usr/share/vim/vim73/pydiction
  
• 　　cp complete-dict  /usr/share/vim/vim73/pydiction/
  
• 　　cp pydiction.py  /usr/share/vim/vim73/pydiction/
  

　　3.修改vim配置文件
　　[plain] view plaincopyprint?

• 　　let g:pydiction_location = '/usr/share/vim/vim73/pydiction/complete-dict'
  
• 　　let g:pydiction_menu_height = 20
  

　　OK，测试是否生效吧
