python编程（tab）补全模块
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】
[*][~$]python
[*]Python 2.7.3 (default, Apr 10 2013, 06:20:15)
[*] on linux2
[*]Type "help", "copyright", "credits" or "license" for more information.
[*]>>> import sys
[*]>>> sys.path
[*]['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old',
[*]'/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages',
[*]'/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0',
[*]'/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/ubuntuone-client',
[*]'/usr/lib/python2.7/dist-packages/ubuntuone-control-panel', '/usr/lib/python2.7/dist-packages/ubuntuone-couch',
[*]'/usr/lib/python2.7/dist-packages/ubuntuone-installer', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol']
[*]>>>
从上面看出python在我电脑上的路径是/usr/lib/python2.7
2.切换至该目录写个startup.py的脚本,脚本目录就是处理python中<tab>事件，脚本内容如下
[*]#!/usr/bin/python
[*]# python startup file
[*]
[*]import sys
[*]import readline
[*]import rlcompleter
[*]import atexit
[*]import os
[*]# tab completion
[*]readline.parse_and_bind('tab: complete')
[*]# history file
[*]histfile = os.path.join(os.environ['HOME'], '.pythonhistory')
[*]try:
[*] readline.read_history_file(histfile)
[*]except IOError:
[*] pass
[*]atexit.register(readline.write_history_file, histfile)
[*]
[*]del os, histfile, readline, rlcompleter
3.切换至自己主目录
[*]cd
[*][~$]vi .bashrc
4. 增加环境变量
[*]#for python
[*]export PYTHONSTARTUP=/usr/lib/python2.7/startup.py
5.配置环境变量生效
[*][~$]source .bashrc
PYTHONSTARTUP是什么东西呢？
[*]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 thatobjects definedorimported 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:

2.拷贝致相应的目录
[*]unzippydiction-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
[*]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
