#To build a .tar.gz for an entire directory tree:

def make_tarfile(output_filename, source_dir):
    with tarfile.open(output_filename, "w:gz") as tar:
        tar.add(source_dir, arcname=os.path.basename(source_dir))

First, "with" will not work in this instance. GzipFile() does not support the __enter__() and __exit__() methods required to use "with".

You have to open the tar in regular fashion way.
Second, os.path.basename requires the import of sys


Perhaps a guide example:
Code:
#!/usr/bin/python

import tarfile
import sys

output_filename = 'etc.tar'
source_dir = '/etc/'

#To build a .tar.gz for an entire directory tree:

def make_tarfile(output_filename, source_dir):
    tar = tarfile.open(output_filename, "w:gz")
    try:
        tar.add(source_dir, arcname=os.path.basename(source_dir))
    finally:
        print 'finished'
        tar.close()

make_tarfile (output_filename, source_dir)

Not tested.

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.
