...package was installed by a distro package manager, removing or upgrading it in a way that would satisfy a Python-specific package manager will generally leave a distro package manager in an inconsistent state. This document also uses phrases like "external package manager" or "system's package manager" to refer to a distro package manager in certain contexts. shadow To shadow an installed Python package is to cause some other package to be preferred for imports without removing any files from t...
...packages available through PyPI, the Python Package Index. We recommend you use the pip tool to simplify installing and managing additional packages. pip is included with Python 3.4 releases; for earlier releases, follow the pip install instructions. Among the packages available through PyPI are some that are specifically for OS X environments. Among these are: pyobjc which provides a bridge between Python and Objective-C, allowing you to write full-featured native Cocoa applications in pure...
...packages get confused a lot. That's not their fault; that's because the volunteers who maintain the packaging tools don't have enough time to get everything organized so that it's clear and easy to use. In the last few years, the PSF has gotten grants and used that money to massively improve packaging. We overhauled PyPI and we're making pip more consistent, with genuine attention to user experience. With more funding, we can finally make managing packages pleasant as programming in Python. Sum...
...package metadata (aka PKG-INFO) files that can be read by pkg_resources to identify what distributions are already on sys.path. In environments where Python packages are installed using system package tools (like RPM), the pkg_resources module provides an API for detecting what versions of what packages are installed, even if those packages were installed via the distutils instead of setuptools. Implementation and Documentation The pkg_resources implementation is maintained in the Python SVN ...
...package managers such as pip (i.e., package managers that support TUF metadata). The entire process is transparent to the end-users (using a package manager that supports TUF) that download distributions from PyPI. The first three subsections (Cryptographic Signature Scheme, Cryptographic Key Files, and Key Management) cover the cryptographic components of the developer release process. That is, which key type PyPI supports, how keys may be stored, and how keys may be generated. The two subse...
...package into a freshly installed Python requires first identifying an appropriate package manager and then installing it. Even on systems that do have a platform package manager, it is unlikely to include every package that is available on the Python Package Index, and even when a desired third-party package is available, the correct name in the platform package manager may not be clear. This means that, to work effectively with the Python Package Index ecosystem, users must know which package m...
...package manager wants to check for updates, it asks TUF to do the work. That is, a package manager never has to deal with this additional metadata or understand what's going on underneath. If TUF reports back that there are updates available, a package manager can then ask TUF to download these files from PyPI. TUF downloads them and checks them against the TUF metadata that it also downloads from the repository. If the downloaded target files are trustworthy, TUF then hands them over to the pac...
...package manager. One of Pythons biggest strengths is in the huge ecosystem of libraries and projects that have been built on top of it, most of which are distributed through PyPI. However, in order to benefit from this wide ecosystem meaningfully requires end users, some of which are going to be new, to make a decision on which package manager they should get, how to get it, and then finally actually installing it first. Furthermore, alternative implementations of Python are recognizing the ben...
...package managers like pip to download and verify distributions with TUF, a few extra files MUST be added to PyPI. These extra repository files are called TUF metadata, and they contain such information as which keys can be trusted, the cryptographic hashes [33] of files, signatures, metadata version numbers, and the date after which the metadata should be considered expired. When a package manager wants to check for updates, it asks TUF to do the work. That is, a package manager never has ...
...Package Index lists thousands of third party modules for Python. Web and Internet Development Python offers many choices for web development: Frameworks such as Django and Pyramid. Micro-frameworks such as Flask and Bottle. Advanced content management systems such as Plone and django CMS. Python's standard library supports many Internet protocols: HTML and XML JSON E-mail processing. Support for FTP, IMAP, and other Internet protocols. Easy-to-use socket interface. And the Package Index ha...

...package management policies of many linux distributions' system package managers [14], [15]. The primary purpose of this is cross-distro compatibility. Furthermore, manylinux1 wheels on PyPI occupy a different niche than the Python packages available through the system package manager. The decision in this PEP to encourage departure from general Linux distribution unbundling policies is informed by the following concerns: In these days of automated continuous integration and deployment pipel...

...package manager tools can take into account Python packages that a user has privately installed. AMK wonders: what does setup.py do if it's told to install packages to a directory not on sys.path? Does it write an install-db directory to the directory it's told to write to, or does it do nothing? Should the package-database file itself be included in the files list? (PJE would think yes, but of course it can't contain its own checksum. AMK can't think of a use case where including the DB file...

Shamika is performing outreach to Python users to help the PSF better understand the landscape, identify fundable initiatives, seek grants, oversee funded projects, and report on their progress and results to improve Python packaging for all users. To continue the above initiatives, the PSF will need to generate USD 325,000 per year. To hire additional folks for either initiative (in demand), the PSF will need USD 500,000+ per year. The amount of funding required is ...
