In general, you can't, as Python 3000 hasn't been nailed down yet.

You shouldn't be asking "How do I write for a language that doesn't exist
yet?" but instead should ask:

(1) How far away is Python 3000?

Years away, although not that many years. Three? Four?

(2) Will there be automated tools for converting source code from Python 2
to Python 3000?

Almost certainly.

(3) Once Python 3000 is released, will Python 2 still be supported and if
so, for how long?

I'm sure there will be a nice long transition period, and if the Python
developers don't want to support Python 2, it will be a wonderful
opportunity for some commercial operation to charge for support.
