Yes but having a problem on how to use sys.argv to check every argument against a set of options. I'm just starting playing in python as I would need to use arithmetic computations which are messy to do using csh.

The arguments passed will be something like this:

Code:
python myscript.py -FDRW1=file1 -FDRW2=file2- 		@page { size: 8.5in 11in; margin: 0.79in } 		P { margin-bottom: 0.08in } 	-->

I get each arguments e.g. -FDRW1=file1 and seperate the two things on either side of '='.

Have got something like this coded in a csh script. Need to do something similar.

Code:
  set narg = $#argv
  while ($iarg < $narg)

    MATH iarg = $iarg + 1
    set arg = $argv[$iarg]
    set opt = ` echo $arg | awk 'BEGIN { FS="=" } { print $1 }' `
    set par = ` echo $arg | awk 'BEGIN { FS="=" } { print $2 }' `

# Change options to upper case.
# Use tr "[A-Z]" "[a-z]" to change from upper to lower case)
    set opt = ` echo $opt | tr "[a-z]" "[A-Z]" `
    echo "opt = $opt"

    switch ($opt)
    case "-FDRW1":
        set Afdrw1 = $par
        set fdrw1 = `echo $Afdrw1 | awk 'BEGIN {FS=".log"} {print $1}'`
        set nxz = `echo $fdrw1 | awk 'BEGIN{FS="-"} {print $NF}'`
        set optfdrw1 = 1
        set optfdrw = 1
        breaksw
    case "-FDRW2":
        set Afdrw2 = $par
        set fdrw2 = `echo $Afdrw2 | awk 'BEGIN {FS=".log"} {print $1}'`
        set optfdrw2 = 1
        set optfdrw = 1
        breaksw
   default:
      set Aerr = $arg
      set ierr = 1
      breaksw
    endsw

  end   # while

dh_python

DH_PYTHON(1)							     Debhelper							      DH_PYTHON(1)

NAME

       dh_python - calculates Python dependencies and adds postinst and prerm Python scripts (deprecated)

SYNOPSIS

       dh_python [debhelperoptions] [-n] [-V version] [moduledirs...]

DESCRIPTION

       Note: This program is deprecated. You should use dh_pysupport or dh_pycentral instead. This program will do nothing if debian/pycompat or a
       Python-Version control file field exists.

       dh_python is a debhelper program that is responsible for generating the ${python:Depends} substitutions and adding them to substvars files.
       It will also add a postinst and a prerm script if required.

       The program will look at Python scripts and modules in your package, and will use this information to generate a dependency on python, with
       the current major version, or on pythonX.Y if your scripts or modules need a specific python version. The dependency will be substituted
       into your package's control file wherever you place the token ${python:Depends}.

       If some modules need to be byte-compiled at install time, appropriate postinst and prerm scripts will be generated. If already byte-
       compiled modules are found, they are removed.

       If you use this program, your package should build-depend on python.

OPTIONS

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

	   Note: only /usr/lib/site-python, /usr/lib/python?.?/site-packages and the extra names on the command line are searched for binary (.so)
	   modules.

       -V version
	   If the .py files your package ships are meant to be used by a specific pythonX.Y version, you can use this option to specify the
	   desired version, such as 2.3. Do not use if you ship modules in /usr/lib/site-python.

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