linux下Python tab补全功能代码

1、在学习linux的童鞋都用惯了tab补全功能,从而在学习Python的同时,一是为了方便,二是可以看到更多的关于Python命令下的知识。

2、配置步骤:

(1) 在linux下键入这样的代码:

vim tab.py

#!/usr/bin/python

# python tab 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

(2)查看路径

[[email protected] ~]#python
Python 2.6.6 (r266:84292, Jan 22 2014, 09:42:36) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/usr/lib64/python26.zip', '/usr/lib64/python2.6', '/usr/lib64/python2.6/plat-linux2', '/usr/lib64/python2.6/lib-tk', '/usr/lib64/python2.6/lib-old', '/usr/lib64/python2.6/lib-dynload', '/usr/lib64/python2.6/site-packages', '/usr/lib64/python2.6/site-packages/gtk-2.0', '/usr/lib/python2.6/site-packages']

Python的默认路径为:/usr/lib64/python2.6/site-packages

(3)将上面的脚本拷贝到默认路径下

cp  tab.py  /usr/lib64/python2.6/site-packages

3、操作:

在Python视图下导入tab,即:

import tab

总结:以上就是简单的python tab 补全配置。
