超简python命令行tab一键补全方法

玩转Linux的朋友们，还在为python默认的无tab补全而烦恼吗？

下面是在下的一个解决方法，希望能帮助到新入学python的学者。

第一步：编写一键补全脚本tab.py

[[email protected]~]#vim tab.py

#!/usr/bin/env python

import sys

import readline

import rlcompleter

import atexit

import os

#tab completion

readline.parse_and_bind(‘tab: complete‘)

第二步：进入python交互模式，查看python模块导入的选择顺序

[[email protected] ~]# python

Python 2.7.5 (default, Nov 20 2015, 02:00:19)

[GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import sys

>>> sys.path

[‘‘, ‘/usr/lib64/python27.zip‘, ‘/usr/lib64/python2.7‘, ‘/usr/lib64/python2.7/plat-linux2‘, ‘/usr/lib64/python2.7/lib-tk‘, ‘/usr/lib64/python2.7/lib-old‘, ‘/usr/lib64/python2.7/lib-dynload‘, ‘/usr/lib64/python2.7/site-packages‘, ‘/usr/lib64/python2.7/site-packages/gtk-2.0‘, ‘/usr/lib/python2.7/site-packages‘]

>>>

第三步：拷贝一键补全脚本到python模块默认路径/usr/lib64/python2.7

[[email protected] ~]cp tab.py /usr/lib64/python2.7/

第四步：导入一键补全模块

[[email protected] ~]# python

Python 2.7.5 (default, Nov 20 2015, 02:00:19)

[GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import tab

>>> import sys

>>> sys.   ——双tab

sys.__class__(              sys.exitfunc(

sys.__delattr__(            sys.flags
