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：
