Here in Ubuntu, we make and promote opinionated choices with the intent of making it easier for our users and developers. There are also lots of opinions on how to best port and support Python 3. There are lots of resources on the 'net for porting to Python 3, but some may be difficult to find or follow. How can we move Python 2 to universe given our intertwined build process and cross-pocket restrictions?Ĭan we better support PyPy and other alternative implementations (let's work with Debian on this).Python 3 only on the default installs for desktop, server, touch, snappy images.Open bugs on Python packages in the archive: In Ubuntu python-minimal is an Essential package.Hopefully, these deltas are even smaller. The above wiki already describes where Debian deviates from upstream Python, and this section will outline how Ubuntu deviates from Debian. Packaging best practices (including Python 3) for Python libraries in Debian

Thanks to Neil Wallace for putting this up. Here's a nice webified version of Barry's IRC tutorial on Python packaging.

This was an effective model for both the Python 2.7 transition and the dh_python2 helper transition. Often, we can initiate big changes in Ubuntu first, using it to blaze a trail, and then systematically push those changes up into Debian, so that we can eventually remove as much of the delta from Ubuntu as possible. A useful way to look at it is this: because Ubuntu and Debian have different release cycles, namely that Ubuntu uses timed releases and Debian uses release-when-ready, we can use these to our advantage. The best thing to do is to start with the Python on Debian wiki page, since we inherit as much as possible from Debian, and we strongly encourage working with the great Debian Python teams to push our changes upstream. Here is everything you ever wanted to know about Python on Ubuntu.
