python 中TAB空格补全

直接放到python运行的目录下面，

#pyhton 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

使用方法：

root@kali:~/python# vim tab.py

root@kali:~/python# python
