python <tab>自动补全

1.获取python目录【我使用的是64位ubuntu系统】

1. [~$]python  

2. Python 2.7.3 (default, Apr 102013, 06:20:15)  

3. [GCC 4.6.3] on linux2  

4. Type "help", "copyright", "credits"or"license"for more information.  

5. >>> import sys  

6. >>> sys.path  

7. ['', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old',  

8. '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages',  

9. '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0',  

10. '/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/ubuntuone-client',  

11. '/usr/lib/python2.7/dist-packages/ubuntuone-control-panel', '/usr/lib/python2.7/dist-packages/ubuntuone-couch',  

12. '/usr/lib/python2.7/dist-packages/ubuntuone-installer', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol']  

13. >>>  

从上面看出python在我电脑上的路径是  /usr/lib/python2.7

2.切换至该目录写个tab.py的脚本,脚本目录就是处理python中<tab>事件，脚本内容如下：

1. #!/usr/bin/python

2. # python startup file

4. import sys  

5. import readline  

6. import rlcompleter  

7. import atexit  

8. import os    

9. # tab completion

10. readline.parse_and_bind('tab: complete')  

11. # history file

12. histfile = os.path.join(os.environ['HOME'], '.pythonhistory')  

13. try:  

14.    readline.read_history_file(histfile)  

15. except IOError:  

16.    pass

17. atexit.register(readline.write_history_file, histfile)  

19. del os, histfile, readline, rlcompleter  

3.切换至自己主目录

[plain]view plaincopyprint?

1. [/usr/lib/python2.7$]cd  

2. [~$]vi .bashrc  

4. 增加环境变量

[plain]view plaincopyprint?

1. #for python  

2. export PYTHONSTARTUP=/usr/lib/python2.7/startup.py  

5.配置环境变量生效

[plain]view plaincopyprint?

1. [~$]source .bashrc  

2.
