1、安装readline

python -m pip install pyreadline

2、编写tab.py

#!/usr/bin/python
# -*- coding:utf-8 -*-
__Author__ = "YoungCheung"
import sys
import readline
import rlcompleter
import atexit
import os
readline.parse_and_bind('tab: complete')
# windows
histfile = os.path.join(os.environ['HOMEPATH'], '.pythonhistory')
# linux
# 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

3、保存文件并放到Python Lib下（如：C:\Python27\Lib）

4、测试效果

import tab
