> The type corresponding to "str" from Python 2.* in Py3k is "bytes" so at

> "str", not "bytes". However I believe it's not too hard to encode new

Have you read:


As much as could be done was worked out quite a while back. I don't
quite understand why PJE is ignoring/forgetting about that list in the
amendments page.

I haven't read the bug reports properly yet, but some of the comments
in the thread says certain things are broken yet that is what was
worked out already as way of doing it.

Have you tried out mod_wsgi (source from subversion repository), which
also has been ported to Python 3.0 already as per proposals in that
amendments page.

When get chance I will read bug reports.
