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. (default, Aug  , ::)
 [GCC 4.4.  (Red Hat 4.4.-)] 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./site-packages/

 

4、验证结果

 

 [root@sun ~]# python
 Python 2.7. (default, Aug  , ::)
 [GCC 4.4.  (Red Hat 4.4.-)] 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(
