You say you aren't trying to go that route, but that is exactly what your "desired output" and your "re-looping" show in post #1 in this thread.

I don't know what "pipe hex the python script to the text file" means.

I don't know what "print the python script against the text file" means.

By definition a text file contains a sequence of zero or more lines of text. I don't know what "Using the text file as a place holder for lines." means.

Please explain clearly in English what you are trying to do and show us (small) sample input files and the exact output you hope to produce.

Note that if you want all of the combinations of millions of lines (10**9) from one file with millions of lines (10**9) from another file you are talking about quadrillions of combinations (10**9 * 10**9 = 10**18) (i.e., quadrillions of lines of output).

LEARN ABOUT DEBIAN

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_python2 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.

CONFORMS TO

       Debian policy, version 3.5.7

       Python policy, version 0.3.7

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
