Python regular expression screen scrub
Hi

I am trying to write a python script that executes a command to screen scrub results below
I will appreciate it very much if you can help me with a python script that can
pick the percentage USAGE in the second column based on the supplied queue number in the first column

Code:
import re
content = """NUMBER of Queues = 5
SYSTEM Treshold = 80%
  ==================================================================

QUEUE   USAGE   TOTAL book1   book2

------------------------------------------------------------------

0001 18%   822   481    98  

0002 16%   345   765    88  

0003 10%   400   300   166  

0004 15%   994   322    177  

0005 17%   348   297    131  

---------------------------------------------------------- """

m = re.match("(0001)/(\d{%})", content)           
if m:
    print m.group(0)      
    print m.group(1)

When i run this from the command prompt nothing shows up

I was able to get this screen scrub done using php preg_match_all
but i want to do the same with the re module in python.

Please suggestions and help will be very much appreciated

Thanks

NAME

       irunner - interactive runner interface

SYNOPSIS

       irunner [options] file_to_run

DESCRIPTION

       irunner	is  an	interface to the various interactive runners available in IPython's irunner module.  It can used to run scripts as if they
       where typed up interactively.

       The already implemented runners are listed below; adding one for a new program is a trivial task, see the source for examples.

OPTIONS

       -h, --help
	      show this help message and exit

       --ipython
	      IPython interactive runner (default).

       --python
	      Python interactive runner.

       --sage SAGE interactive runner.

EXAMPLE

       irunner.py --python -- --help will pass --help to the python runner.  Similarly, irunner.py --ipython -- --interact script.ipy
