system :Red Hat Enterprise Linux Server release 5.6 (Tikanga)1、获取python目录

1 2 3 4 5 6 7

[iyunv@test ~]# python Python 2.4.3 (#1, Dec 10 2010, 17:24:35) [GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.path ['', '/usr/lib64/python24.zip', '/usr/lib64/python2.4', '/usr/lib64/python2.4/plat-linux2', '/usr/lib64/python2.4/lib-tk', '/usr/lib64/python2.4/lib-dynload', '/usr/lib64/python2.4/site-packages', '/usr/lib64/python2.4/site-packages/Numeric', '/usr/lib64/python2.4/site-packages/gtk-2.0', '/usr/lib/python2.4/site-packages']

得知python目录/usr/lib64/python2.4
2、切换至python目录编写startup.py脚本,处理python中<tab>事件
内容如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

[iyunv@test ~]# cd /usr/lib64/python2.4/ [iyunv@test python2.4]# vi startup.py #!/usr/bin/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

3、切换至主目录增加环境变量并使生效

1 2 3 4 5

[iyunv@test python2.4]# cd [iyunv@test ~]# vi .bashrc #在最后一行添加： #for python export PYTHONSTARTUP=/usr/lib64/python2.4/startup.py

1	[iyunv@test ~]# source .bashrc

4、验证

1 2 3 4 5 6 7 8 9

[iyunv@test ~]# python Python 2.4.3 (#1, Dec 10 2010, 17:24:35) [GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.path sys.path                 sys.path_importer_cache sys.path_hooks            >>> sys.path
