Python:Picking values from a table

Hi

I 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
Thanks in advance.

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

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

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
