How do I install the latest Python version in Ubuntu? [duplicate]

How to update to the latest Python version in Ubuntu? I tried sudo apt-get install python3 but it says that the current (3.3.1) is already the latest.

Try adding this PPA (notice, I haven't tested it, but it looks fine): https://launchpad.net/~fkrull/+archive/deadsnakes

To do this, open a terminal, and run this:

sudo apt-add-repository ppa:fkrull/deadsnakes # Adds the PPA
sudo apt-get update # Updates the lists

And then run the system updates (I would recommend this over sudo apt-get install python3 because other packages may need to be updated for it to work fine):

sudo apt-get dist-upgrade # dist-upgrade might be needed if python3
                          # needs to install or remove packages
                          # for it to work

Ubuntu 13.04 comes with pre-loaded python3 (3.3.2). So you may already have python3 (3.3.2) installed. try python3 in terminal instead of just python
