'''setuptools''' is a [[package development process]] library designed to facilitate packaging Python projects by enhancing the Python standard library {{mono|distutils}} (distribution utilities). It includes:
* Python package and module definitions
* Distribution package metadata
* Test hooks
* Project installation
* Platform-specific details
* Python 3 support

==History{{anchor|Distribute}}==
On 2004-03-17, Phillip J. Eby announced the existence of the project.<ref>{{cite web |last1=Eby |first1=Phillip J. |title="setuptools" package preview |url=https://mail.python.org/pipermail/distutils-sig/2004-March/003758.html |website=Distutils-SIG |date=7 March 2004 |access-date=17 July 2021}}</ref> In 2013, '''Distribute''', a fork of setuptools, was merged back into setuptools 0.7.

Python '''wheels''' have replaced '''eggs'''.<ref>{{Cite web|url=https://pypi.org/project/wheel/|title = Wheel: A built-package format for Python}}</ref>

'''Python eggs''' are a way of bundling additional information with a Python project, that allows the project's dependencies to be checked and satisfied at runtime, as well as allowing projects to provide [[plug-in (computing)|plugins]] for other projects.

{{quote|"Eggs are to Pythons as [[JAR (file format)|Jars]] are to Java..."||source = http://peak.telecommunity.com/DevCenter/PythonEggs}}

==Package manager{{anchor|EasyInstall}}==
Python '''pip''' has replaced '''EasyInstall'''.<ref>jaraco: [https://github.com/pypa/setuptools/issues/917 Replace easy_install with pip install''.] Jan 9, 2017.</ref>

''EasyInstall'' is a package manager for Python that provides a standard format for distributing Python programs and [[library (computing)|libraries]] (based on the Python Eggs format). EasyInstall is a module bundled with setuptools.<ref>http://peak.telecommunity.com/DevCenter/setuptools September 1, 2009</ref> It is analogous to [[RubyGems]] for [[Ruby (programming language)|Ruby]].

EasyInstall is not a fully fledged package manager. It cannot list local packages nor update them all. [[Pip (package manager)|Pip]] and [[Python Package Manager]] (PyPM) are Python applications designed to fulfill a similar role as EasyInstall. The Distribute fork was created specifically due to the lack of progress in EasyInstall development.<ref>{{cite web|url=https://ziade.org/2009/07/19/the-strange-world-of-packaging-forking-setuptools/|title=The strange world of packaging – forking setuptools|author=Tarek Ziade|accessdate=10 October 2011|archive-date=2 May 2012|archive-url=https://web.archive.org/web/20120502153925/http://ziade.org/2009/07/19/the-strange-world-of-packaging-forking-setuptools/|dead-url=yes}}</ref>

By default, EasyInstall looks in the [[Python Package Index]] (PyPI) for the desired packages and uses the metadata there to download and install the package and its dependencies.
