IMHO, although I've tested only sqlite, I think in python3 we can use the same drivers (psycopg2 for python3) and they behave mostly the same as in python2
About the "new" wsgi spec, I don't see major changes, they are "cosmetic" regarding str/byte/unicode (in fact, pep-333 wsgi is version 1.0, pep-3333 for py3k is wsgi 1.0.1) Indeed, to get rid of unicode, I've done something similar to whet wsgi pep suggest http://www.python.org/dev/peps/pep-3333/#a-note-on-string-types 2to3 solved a lot of automatic issues (new syntaxis, moved libraries, etc.) but some manual work must be done, it would be great to backport that changes so the same web2py codebase could be used in py2 and py3k (after using 2to3). Rocket, cherrypy and bootle already are following that approach (see "if PY3K:" blocks in rocket or bootle) Best regards Mariano Reingart http://www.sistemasagiles.com.ar http://reingart.blogspot.com On Mon, Oct 24, 2011 at 11:48 AM, Massimo Di Pierro <massimo.dipie...@gmail.com> wrote: > Most of web2py was written with python 3 in mind.
