For a guide to +installing other Python projects, refer to the +:ref:`installation guide <installing-index>`. + +.. note:: + + For corporate and other institutional users, be aware that many + organisations have their own policies around using and contributing to + open source software. Please take such policies into account when making + use of the distribution and installation tools provided with Python. + + +Key terms +========= + +* the `Python Package Index <https://pypi.python.org/pypi>`__ is a public + repository of open source licensed packages made available for use by + other Python users +* the `Python Packaging Authority + <http://packaging.python.org/en/latest/future.html>`__ are the group of + developers and documentation authors responsible for the maintenance and + evolution of the standard packaging tools and the associated metadata and + file format standards. They maintain a variety of tools, documentation + and issue trackers on both `GitHub <https://github.com/pypa>` and + `BitBucket <https://bitbucket.org/pypa/>`__. +* ``distutils`` is the original build and distribution system first added to + the Python standard library in 1998. While direct use of ``distutils`` is + being phased out, it still laid the foundation for the current packaging + and distribution infrastructure, and it not only remains part of the + standard library, but its name lives on in other ways (such as the name + of the mailing list used to coordinate Python packaging standards + development). + + +Open source licensing and collaboration +======================================= + +In most parts of the world, software is automatically covered by copyright. +This means that other developers require explicit permission to copy, use, +modify and redistribute the software. + +Open source licensing is a way of explicitly granting such permission in a +relatively consistent way, allowing developers to share and collaborate +efficiently by making common solutions to various problems freely available. +This leaves many developers free to spend more time focusing on the problems +that are relatively unique to their specific situation. + +The distribution tools provided with Python are designed to make it +reasonably straightforward for developers to make their own contributions +back to that common pool of software if they choose to do so. + +The same distribution tools can also be used to distribute software within +an organisation, regardless of whether that software is published as open +source software or not. + + +Installing the tools +==================== + +The standard library does not include build tools that support modern +Python packaging standards, as the core development team has found that it +is important to have standard tools that work consistently, even on older +versions of Python. + +The currently recommended build and distribution tools can be installed +using ``pip``:: + + pip install setuptools wheel twine + + +Reading the guide +================= + +The Python Packaging User Guide covers the various key steps and elements +involved in creating a project + +* `Project structure`_ +* `Building and packaging the project`_ +* `Uploading the project to the Python Package Index`_ + +.. _Project structure: \ + http://packaging.python.org/en/latest/tutorial.html#creating-your-own-project +.. _Building and packaging the project: \ + http://packaging.python.org/en/latest/tutorial.html#building-packaging-your-project +.. _Uploading the project to the Python Package Index: \ + http://packaging.python.org/en/latest/tutorial.html#building-uploading-your-project-to-pypi + + +How do I...? +============ + +These are quick answers or links for some common tasks. + +... choose a name for my project? +--------------------------------- + +This isn't an easy topic, but here are a few tips: + +* check the Python Package Index to see if the name is already in use +* check popular hosting sites like GitHub, BitBucket, etc to see if there + is already a project with that name +* check what comes up in a web search for the name you're considering +* avoid particularly common words, especially ones with multiple meanings, + as they can make it difficult for users to find your software when + searching for it + + +... create and distribute binary extensions? +-------------------------------------------- + +This is actually quite a complex topic, with a variety of alternatives +available depending on exactly what you're aiming to achieve. See the +Python Packaging User Guide for more information and recommendations. + +.. seealso:: + + `Python Packaging User Guide: Binary Extensions + <http://packaging.python.org/en/latest/extensions.html>`__ + +.. other topics: + + Once the Development & Deployment part of PPUG is fleshed out, some of + those sections should be linked from new questions here (most notably, + we should have a question about avoiding depending on PyPI that links to + http://packaging.python.org/en/latest/deployment.html#pypi-mirrors-and-caches) |
