Pythonpy supports both python2 and python3.

For python3 install, use:

sudo pip3 install -I pythonpy

This should give an output like:

Notice that this created the following executables:

• py
• py3
• py3.3

All of these will run pythonpy using python3. Use py -V to determine the Python version if you aren't sure. If you want python2 and python3 support on the same machine, you can subsequently run:

sudo pip install -I pythonpy

Which will create the executables:

• py
• py2
• py2.7

This will of course overwrite py, but not py3.
