python <tab>自动补全

而温柔

1.获取python目录【我使用的是64位ubuntu系统】

[~$]python  
Python 2.7.3 (default, Apr 102013, 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tab.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



[/usr/lib/python2.7$]cd  
[~$]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
