Packaging python script to Debian follows strict instructions, using the following instructions, most of the steps can be skipped hence making it easy and fast.
If you like video go to https://www.youtube.com/watch?v=a9GzDZB5VeU. This video doesn't show setup.py file creating which is required, but excluding that portion everything is same as below.

$mkdir mymood
$cd mymood
$mkdir debian
$mkdir mymoodGoto mymood/mymood directory and paste mymood.py script as shown in project structure.
Within mymood/mymood create __init__.py
Within mymood/mymood directory create command_line.py. setup.py needs this to run script from bash just by typing mymood.
$vim command_line.pycopy the following into command_line.py
from mymood import analyze
def main():
analyze()Create a setup.py file in mymood directory as shown in project structure above.
The below code is simple and minimal setup.py for mymood, copy and change as you require.
from setuptools import setup
setup(name='mymood',
version='0.1',
description='your mood analyzer',
author='mp',
author_email='[email protected]',

entry_points = {
'console_scripts': ['mymood=mymood.command_line:main'],
},
zip_safe=False)Console scripts is used to run the script from terminal. So from bash you can just type mymood and run the script.
$mkdir debianDevscripts package is needed to create changelog file.
$cd debian
$sudo apt-get install devscripts
$dch --createNow edit the file as follows:

Also not that you use tab before dh, not spaces

setup.pyAs you can see we get mymood_1.0_all.deb package wich can be installed by "ubuntu software center".
Ubuntu Software Center is recomended as it automatically installs dependencies
or
simply
$sudo dpkg -i mymood_1.0_all.deb <-- this command throws errors if dependencies not satisfied. Use ubuntu softare center.Video for the above fosshelp blog post: https://www.youtube.com/watch?v=a9GzDZB5VeU.
