python添加tab键提示

新建一个tab.py脚本

#!/usr/bin/python

import sys
import readline
import rlcompleter
import atexit
import os
readline.parse_and_bind('tab:complete')
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

进入python,然后执行import tab

这样就成功添加tab键提示了。
