1.解决方案：自行导入tab键的模块--创建tab.py模块文件

 

 1 #!/usr/bin/env python
 2 # python startup file 
 3 import sys
 4 import readline
 5 import rlcompleter
 6 import atexit
 7 import os
 8 # tab completion 
 9 readline.parse_and_bind('tab: complete')
10 # history file 
11 histfile = os.path.join(os.environ['HOME'], '.pythonhistory')
12 try:
13     readline.read_history_file(histfile)
14 except IOError:
15     pass
16 atexit.register(readline.write_history_file, histfile)
17 del os, histfile, readline, rlcompleter

 

2.tab.py文件放到/usr/lib/python2.7
3.先在python的交互界面中导入一下
1 xpleaf@py:~/seminar6/day1$ python
2 Python 2.7.3 (default, Aug  1 2012, 05:14:39) 
3 [GCC 4.6.3] on linux2
4 Type "help", "copyright", "credits" or "license" for more information.
5 >>> import sys    ===>导入sys模块只是为了下面对tab键补全做测试
6 >>> import tab    ===>这才是重点
