From my perspective, I don't understand why you do not do all the text processing and system call in python, since your command starts out with python.

python works just fine to process text, make system calls, etc.

For example, you can run the rpm -qa command in Python as follows:

Code:
import os
os.system('rpm -qa')

Or a more likely syntax, here is an example:

Code:
import subprocess 
time = subprocess.check_output('date')
print 'Now the time is', time

Since your script starts out with python, why not do the rest of the processing in python?

LEARN ABOUT DEBIAN

dh_pysupport

DH_PYSUPPORT(1) 						  python-support						   DH_PYSUPPORT(1)

NAME

       dh_pysupport - use the python-support framework to handle Python modules

SYNOPSIS

       dh_pysupport [debhelper options] [-V X.Y] [-X item [...]] [-n] [module dirs ...]

DESCRIPTION

       dh_pysupport is a debhelper program that will scan your package, detect public modules in /usr/lib/pythonX.Y/site-packages, and move them
       to the shared Python modules location. It will generate appropriate postinst/prerm scripts to byte-compile modules installed there for all
       available python versions.

       It will also look for private Python modules and will byte-compile them with the current Python version. You may have to list the
       directories containing private Python modules.

       If a file named debian/pyversions exists, it is used to determine the python versions with which the package can work.

       Appropriate dependencies on python-support, python and pythonX.Y are put in ${python:Depends}.  The ${python:Versions} and
       ${python:Provides} optional substitution variables are made available as well.

OPTIONS

       module dirs
	   If your package installs private python modules in non-standard directories, you can make dh_pysupport check those directories by
	   passing their names on the command line. By default, it will check /usr/lib/$PACKAGE, /usr/share/$PACKAGE, /usr/lib/games/$PACKAGE and
	   /usr/share/games/$PACKAGE

       -n, --noscripts
	   Do not modify postinst/postrm scripts.

       -d  This option is deprecated.

       -V X.Y
	   Force private modules to be bytecompiled with the specific X.Y python version, regardless of the default python version on the system.

       -X item, --exclude=item
	   Exclude files that contain "item" anywhere in their filename from being taken into account to generate the python dependency. It also
	   excludes them from byte-compilation. You may use this option multiple times to build up a list of things to exclude.

CONFORMS TO

       Python policy as of 2006-08-10

SEE ALSO

       debhelper(7)

       This program is a part of python-support but is made to work with debhelper.
