centos中配置python的tab键自动补全功能

一、首先打开python，观察python的安装路径
[iyunv@localhost ~]# python
Python 3.6.2 (default, Aug 14 2017, 22:12:34)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/usr/local/lib/python36.zip', '/usr/local/lib/python3.6', '/usr/local/lib/python3.6/lib-dynload', '/root/.local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/site-packages']
>>>

二、退出python、进入python目录
[iyunv@localhost ~]# cd /usr/local/lib/python3.6/

三、新建tab.py文件，并且输入配置内容
[iyunv@localhost python3.6]# vim tab.py
输入：

#!/usr/bin/env python
# python 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

四、验证
[iyunv@localhost python3.6]# python
Python 3.6.2 (default, Aug 14 2017, 22:12:34)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux

>>> b

>>> c

>>>
