The long-term plan is to move Sage to Python 3. Here's a couple Trac metatickets that show the progress:

In the mean time, just be aware of the major changes between the two versions and write Python 3-compatible code as much as possible.

To which one should note that the changes are relatively minor compared to, say, learning a different computer language!

The point is that nearly everything you know from Python 3 will be the same in Python 2. And many of the changes already "work" in the version of Python in Sage (see So you might as well get started with Sage!

Many important functions are backported to 2.7 from 3. Others can be enabled like so: from __future__ import print_function . That will give you the format of the python 3 print function. After that you can use the new print modifiers, i.e. print(value, ..., sep=' ', end='\n', file=sys.stdout)
