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?

update-python-modules

UPDATE-PYTHON-MODULES(8)				      System Manager's Manual					  UPDATE-PYTHON-MODULES(8)

NAME

       update-python-modules - byte-compile python modules

SYNOPSIS

       update-python-modules [options] [package.public [...]]

DESCRIPTION

       The update-python-modules command is part of the python-support bundle.

       update-python-modules  is  responsible for the byte-compilation of python modules. When used in byte-compilation mode, it will byte-compile
       modules references in the files given on the command line. When used in	installation  mode,  it  will  byte-compile  them  once  for  each
       installed python version, and will make them available for all of them.

       At  each  invocation,  with  or without arguments, update-python-modules will check for installed python versions, and will build or remove
       modules according to new or removed versions since the last time it was run.

ARGUMENTS

       Arguments must be files or directories located in the /usr/share/python-support directory. Depending on their extension, they  are  treated
       differently.

       package.public
	      A file listing public modules to install for each version. These modules must lie in /usr/share/pyshared or /usr/lib/pyshared.

       package.private
	      A file listing private modules to byte-compile for one Python version.

       package/
	      A legacy directory hierarchy of public modules. The C extensions and portions that change with the Python version are to be found in
	      /usr/lib/python-support/pythonX.Y/package/.

       package.dirs
	      A legacy file listing directories where to find private modules.

OPTIONS

       -h, --help
	      Show summary of options.

       -v, --verbose
	      Detail all actions while they are performed.

       -b, --bytecompile
	      Only accept to work on private modules. When given this option, update-python-modules will fail if passed references to public  mod-
	      ules.

       -i, --install
	      Only  accept  to work on public modules. When given this option, update-python-modules will fail if passed references to public mod-
	      ules.

       -c, --clean
	      Clean modules instead of installing them.

       -a, --rebuild-all
	      Rebuild all private modules. This is necessary when the default python version was changed, for example.

       -f, --force-rebuild-all
	      Clean all modules (public and private), and rebuild them.

FILES

       /usr/lib/pymodules/pythonX.Y/
	      These directories contain the byte-compiled modules for version pythonX.Y.
