1.准备一个脚本如下：

#!/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Python默认的模块存放地址

>>> import sys  >>> sys.path  ['', '/usr/local/python2.7/lib/python2.7/site-packages/distribute-0.6.49-py2.7.egg', '/usr/local/python2.7/lib/python2.7/site-packages/pip-9.0.1-py2.7.egg', '/usr/local/python2.7/lib/python27.zip', '/usr/local/python2.7/lib/python2.7', '/usr/local/python2.7/lib/python2.7/plat-linux2', '/usr/local/python2.7/lib/python2.7/lib-tk', '/usr/local/python2.7/lib/python2.7/lib-old', '/usr/local/python2.7/lib/python2.7/lib-dynload', '/usr/local/python2.7/lib/python2.7/site-packages', '/usr/local/python2.7/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg-info']

3. 创建该脚本到默认模块存放路径

 vi /usr/local/python2.7/lib/python2.7/tab.py

4导入tab模块，验证.

>>> import tab  >>> sys.  sys.__class__(              sys.api_version             sys.hexversion  sys.__delattr__(            sys.argv                    sys.long_info
