Question

Does wxPython have a version for Python 3?

If it does, where can I get it?

Answer 1

Updated news on this question are being posted in the wxpython wiki.
Here you can find everal edits updating the initial answer (first more recent)

December 2011: Great news ! First build of project Phoenix the new wxPython that will support both Python 2.x and 3.x. Current builds are however for python 2.7.

November 2011: Last Update of the wiki is from 19-April-2011. == No news for 3.x 🙁

Tentative wxPython Roadmap

• wxPython “Next Generation”: (ongoing) There has been some discussions off and on over the past couple years about a whole new way to generate the code used for the wxPython extension modules (a.k.a the C++ wrapper code). There has been some design work done towards this goal, and a proof of concept has been implemented. In a nutshell the proof of concept has exceeded all my expectations and I feel that this will be an excellent way to automate much more of the generation of the wrapper code. More information about the goals and design of the new wxPython can be found at ProjectPhoenix, and the source code can be viewed in the wx repository. Although the new approach will make maintenance of wxPython much simpler in the future, it is still a lot of work to make the transition and so it will not become the highest priority task until more of the low-level foundational pieces are completed and verified. In the meantime the current 2.9.x ReleaseSeries will continue to progress using the old technology.

• Python 3.x support: (unknown) It is expected that some things being done for the Next Generation project will make it easier to be able to maintain support for both Python 2.x and 3.x in the same source tree, so I’ve been delaying putting much effort into a Python 3.x port in order to prevent wasting time on something that may end up getting thrown away once the NG switch is made. If that Next Generation project ends up being left on-hold for too long however then I’ll probably revisit this item and move up the priority.

There has been some design work done towards this goal, and the beginnings of some work on tools. However since work was progressing slowly on this I decided to put it on hold for a bit so I could get some of the new features and fixes in the 2.9 release series into the hands of the wxPython developers. I expect to be able to switch my focus back to this goal sometime after the 2.9.1 release. Once the design, plans and tools are complete enough I’ll publish more information about it and open it up for other developers to lend a hand.
• Python 2.7 support: (now) The Windows and OSX build machines have been updated with Python 2.7 and binaries for 2.7 were included with 2.8.11.0 and will be included in future preview builds and releases.
• Python 3.x support: (unknown) I’m hopeful that some things being done for the Next Generation project will make it easier to be able to maintain support for both Python 2.x and 3.x in the same source tree, so I’ve been delaying putting much effort into a Python 3.x port in order to prevent wasting time on something that may end up getting thrown away once the NG switch is made.
