python tab 自动补全

环境Centos6.5   python2.6.6

 

1、编写python的tab自动补全脚本

 

#!/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

2、查看python默认的模块存放路径

 

>>> sys.path
['', '/usr/lib64/python26.zip', '/usr/lib64/python2.6', '/usr/lib64/python2.6/plat-linux2', '/usr/lib64/python2.6/lib-tk', '/usr/lib64/python2.6/lib-old', '/usr/lib64/python2.6/lib-dynload', '/usr/lib64/python2.6/site-packages', '/usr/lib64/python2.6/site-packages/gst-0.10', '/usr/lib64/python2.6/site-packages/gtk-2.0', '/usr/lib/python2.6/site-packages']

3、将 tab.py 拷贝到 默认的模块存放路径

cp  tab.py  /usr/lib/python2.6/site-packages/

或

ln -s ~/tab.py  /usr/lib/python2.6/site-packages/

 

4、使用

>>> import sys
>>> import tab
>>> sys.
