python交互环境tab补齐

>>> import sys

>>> sys.path

['', '/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg', '/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/lib/python2.6/site-packages']

第一个为空，代表着先到当前目录下去查找

tab.py就放到上面的目录下

#!/usr/bin/env python

#coding=utf-8

import sys

import readline

import rlcompleter

import atexit

import os

# tab completion

readline.parse_and_bind('tab: complete')

放到/usr/lib/python2.6/site-packages目录下

import tab

import os

os. 

(tab键就可以使用了）
