Python的自动补全

1、编辑文件 tab.py

 

vi tab.py
 
#!/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

 

2、确认 第三方脚本或模块存放路径

 

[root@sun ~]# python
Python 2.7.12 (default, Aug 23 2016, 16:39:04)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/usr/local/python27/lib/python27.zip', '/usr/local/python27/lib/python2.7', '/usr/local/python27/lib/python2.7/plat-linux2', '/usr/local/python27/lib/python2.7/lib-tk', '/usr/local/python27/lib/python2.7/lib-old', '/usr/local/python27/lib/python2.7/lib-dynload', '/usr/local/python27/lib/python2.7/site-packages']
>>>

3、将编辑好的 tab.py 脚本放到  /usr/local/python27/lib/python2.7/site-packages 目录一份

 

[root@sun ~]# cp tab.py /usr/local/python27/lib/python2.7/site-packages/

 

4、验证结果

 

[root@sun ~]# python
Python 2.7.12 (default, Aug 23 2016, 16:39:04)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import tab
>>> h
hasattr(  hash(     help(     hex(     
>>> h
>>> s
set(           slice(         staticmethod(  sum(           
setattr(       sorted(        str(           super(
