I'm using Ubuntu 14.04 where the default python version is 2.7.

I would love to type python3 to run python 3.4. How can I set that ? (After that, I think I can run python 2.7 by typing python2).

python is just a symlink in bin.
Just run the following command:

ln -s /usr/bin/python3 ~/bin/python

If you want to change back, run:

ln -s /usr/bin/python2 ~/bin/python

This may break many applications that use python to refer to python2. –  i08in May 18 at 9:40
