Here you will find the simplest possible example of using distutils and setup.py:
https://docs.python.org/2/distutils/introduction.html#distutils-simple-example
This assumes that all your code is in a single file and tells how to package a project containing a single module.
Look at this complete example https://github.com/marcindulak/python-mycli of a small python package. It is based on packaging recommendations from https://packaging.python.org/en/latest/distributing.html, uses setup.py with distutils and in addition shows how to create RPM and deb packages.
The project's setup.py is included below (see the repo for the full source):
#!/usr/bin/env python
import os
import sys
from distutils.core import setup
name = "mycli"
rootdir = os.path.abspath(os.path.dirname(__file__))
# Restructured text project description read from file
long_description = open(os.path.join(rootdir, 'README.md')).read()
# Python 2.4 or later needed
if sys.version_info < (2, 4, 0, 'final', 0):
raise SystemExit, 'Python 2.4 or later is required!'
# Build a list of all project modules
packages = []
for dirname, dirnames, filenames in os.walk(name):
if '__init__.py' in filenames:
packages.append(dirname.replace('/', '.'))
package_dir = {name: name}
# Data files used e.g. in tests
package_data = {name: [os.path.join(name, 'tests', 'prt.txt')]}
# The current version number - MSI accepts only version X.X.X
exec(open(os.path.join(name, 'version.py')).read())
# Scripts
scripts = []
for dirname, dirnames, filenames in os.walk('scripts'):
for filename in filenames:
if not filename.endswith('.bat'):
scripts.append(os.path.join(dirname, filename))
# Provide bat executables in the tarball (always for Win)
if 'sdist' in sys.argv or os.name in ['ce', 'nt']:
for s in scripts[:]:
scripts.append(s + '.bat')
# Data_files (e.g. doc) needs (directory, files-in-this-directory) tuples
data_files = []
for dirname, dirnames, filenames in os.walk('doc'):
fileslist = []
for filename in filenames:
fullname = os.path.join(dirname, filename)
fileslist.append(fullname)
data_files.append(('share/' + name + '/' + dirname, fileslist))

- initial version
Here is the utility I wrote to generate a simple setup.py file (template) with useful comments and links. I hope, it will be useful.
sudo pip install setup-py-cli
To generate setup.py file just type in the terminal.
setup-py
Now setup.py file should occur in the current directory.
from distutils.core import setup
from setuptools import find_packages
import os
# User-friendly description from README.md
current_directory = os.path.dirname(os.path.abspath(__file__))
try:
with open(os.path.join(current_directory, 'README.md'), encoding='utf-8') as f:
long_description = f.read()
except Exception:
long_description = ''
setup(
# Name of the package
name=<name of current directory>,

packages=find_packages('.'),

Here is the link to the repository. Fill free to enhance the solution.
I recommend the setup.py of the Python Packaging User Guide's example project.
The Python Packaging User Guide "aims to be the authoritative resource on how to package, publish and install Python distributions using current tools".
You may find the HitchHiker's Guide to Packaging helpful, even though it is incomplete. I'd start with the Quick Start tutorial. Try also just browsing through Python packages on the Python Package Index. Just download the tarball, unpack it, and have a look at the setup.py
file. Or even better, only bother looking through packages that list a public source code repository such as one hosted on GitHub or BitBucket. You're bound to run into one on the front page.
My final suggestion is to just go for it and try making one; don't be afraid to fail. I really didn't understand it until I started making them myself. It's trivial to create a new package on PyPI and just as easy to remove it. So, create a dummy package and play around.
READ THIS FIRST https://packaging.python.org/en/latest/current.html
Installation Tool Recommendations
- Use pip to install Python packages from PyPI.
- Use virtualenv, or pyvenv to isolate application specific dependencies from a shared Python installation.
- Use pip wheel to create a cache of wheel distributions, for the purpose of > speeding up subsequent installations.
- If you’re looking for management of fully integrated cross-platform software stacks, consider buildout (primarily focused on the web development community) or Hashdist, or conda (both primarily focused on the scientific community).
Packaging Tool Recommendations
- Use setuptools to define projects and create Source Distributions.
- Use the bdist_wheel setuptools extension available from the wheel project to create wheels. This is especially beneficial, if your project contains binary extensions.
- Use twine for uploading distributions to PyPI.
This anwser has aged, and indeed there is a rescue plan for python packaging world called
I qoute pythonwheels.com here:
What are wheels?
Wheels are the new standard of python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.
Advantages of wheels
The full story of correct python packaging (and about wheels) is covered at packaging.python.org
For scientific computing (this is also recommended on packaging.python.org, see above) I would consider using CONDA packaging which can be seen as a 3rd party service build on top of PyPI and pip tools. It also works great on setting up your own version of binstar so I would imagine it can do the trick for sophisticated custom enterprise package management.
Conda can be installed into a user folder (no super user permisssions) and works like magic with
conda install
and powerful virtual env expansion.
This option was related to python-distribute.org and is largerly outdated (as well as the site) so let me point you to one of the ready to use yet compact setup.py examples I like:
This quote was taken from the guide on the state of setup.py and still applies:
I add one more point (from me)
I would recommend to get some understanding of packaging-ecosystem (from the guide pointed by gotgenes) before attempting mindless copy-pasting.
Most of examples out there in the Internet start with
from distutils.core import setup
but this for example does not support building an egg python setup.py bdist_egg (as well as some other old features), which were available in
from setuptools import setup
And the reason is that they are deprecated.
Now according to the guide
Warning
Please use the Distribute package rather than the Setuptools package because there are problems in this package that can and will not be fixed.
deprecated setuptools are to be replaced by distutils2, which "will be part of the standard library in Python 3.3". I must say I liked setuptools and eggs and have not yet been completely convinced by convenience of distutils2. It requires
pip install Distutils2
and to install
python -m distutils2.run install
Packaging never was trivial (one learns this by trying to develop a new one), so I assume a lot of things have gone for reason. I just hope this time it will be is done correctly.
