While the expectation is such that people aren't requiring the usage of Python 3 that widely, and most of the distributions haven't picked it up yet, there's some support in the Open Source GIS realm. Thanks to Even Rouault, GDAL 1.7 will have Python 3 support through SWIG, though it will be somewhat limited by numpy not being ported to Python 3.x. libLAS also provides support for Python 3.x via ctypes. I know that Shapely also has some Python 3 support. I am sure there are many others. I would say that Python 3.x is not widely enough used to require *only* Python 3. You must support both the 2.x and 3.x right now (my guess is that you'll probably want to support Python 2.x for at least the next five years as well), either within the same codebase or as two separate sub-libraries that are mostly the same code.

Re: [OSGeo-Discuss] OSGEO projects and Python 3.x
I don't think that we (OpenJUMP) will switch to Python 3.x using Jython soon - nor prepare anything. So we rely on the Jython team anyway. stefan Dave Sampson schrieb: Hey Folks, I am wondering what, if any, projects are preparing or planning for a move to support python 3.x.

RE: [OSGeo-Discuss] OSGEO projects and Python 3.x
Dave, I know I had some problems getting Python 3.X to work on my Windows XP computer a couple of weeks ago. I had no problems with the previous release of Python.
