That depends VERY strongly on the environment in question. > > 2. Get those modules converted to Python 3. The stdlib is there. The rocky bits are being fixed all the time. The other important modules all have strong development communities. Upstream numpy works with Python 3 already. (no release yet) That enables SciPy to update, which they will do.

Also, I myself see no benefit in making PyPI a mirror of everything, as opposed to a useful index of packages that you may or may not want to use. > > 4.

Apparently, some hosters already support Python 3. Web development is a bit of a weak spot at the moment though, and this is problematic, due to WSGI not being quite unicode ready. > > 6.

It's not happening fast, it probably can't, but it *is* happening. Software distributions are including Python 3, and popular modules/packages are starting to support it. Other software is going to move on in its own time. -- http://mail.python.org/mailman/listinfo/python-list
