*  编写一个tab.py文件，内容如下：

import sys
    import readline
    import rlcompleter
    
    if sys.platform == 'darwin' and sys.version_info[0] == 2:
        readline.parse_and_bind("bind ^I rl_complete")
    else:
        readline.parse_and_bind("tab: complete")
    # 如果没有readline 模块， 需要自己安装一个

*  将上述文件放到一个Python 模块搜索路径中

$ python
    >>> import sys
    >>> sys.path
    >>> ['', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/Library/Python/2.7/site-packages', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC', '/Library/Python/2.7/site-packages/setuptools-33.1.1-py2.7.egg']
    
    # 选取一个你有写权限的路径 如 
    # /Library/Python/2.7/site-packages
    # 将tab.p文件拷贝到此路径下
    # $ sudo cp tab.py /Library/Python/2.7/site-packages

*  执行命令行语句, 加入环境变量 PYHTONSTARTUP：
    
        $ echo "export PYTHONSTARTUP=/Library/Python/2.7/site-packages/tab.py" >> /Users/xxx/.bashrc
        
        $ source  /User/xxx/.bashrc
 *  搞定 测试

$ python
    >>> import os
    >>> os.<tab>
    >>> ...
