Do you know some of python and maybe you can show me an example of how to extract those byte sequences using this language.
Thanks in advance.

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.
CONFORMS TO
Debian policy, version 3.5.7
Python policy, version 0.3.7
