Use the Deadsnakes PPA, which includes a range of Python versions packaged for a range of Ubuntu versions, including 3.2 for raring.

sudo apt-add-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python3.2

Ubuntu – Upgrading to python 3.2

Since many programs and libraries rely on Python 2.6 (or python 2.7 in 11.04), and since python 2.x and 3.x are incompatible, you can't upgrade - you can only install python3 alongside python 2.6:

Python 3.1

Luckily, the stable release of Python 3 (3.1.2 at the time of writing this) is provided in the repositories. Just install the python3-all package.

Your interpreter will be /usr/bin/python3 instead of /usr/bin/python.

You can also now type python3 in your terminal when you want to launch Py3 instead of Py2.

Python 3.2

You can, download any version of the python sources from python.org and run
```
./configure
make
sudo make altinstall
```
To be able to compile the python source, you'll need a few packages:
```
sudo apt-get install build-essential libncursesw5-dev libreadline5-dev libssl-dev libgdbm-dev libc6-dev libsqlite3-dev tk-dev libbz2-dev
```
The altinstall option will install the other version of python alongside your existing ones:

It makes sense to, instead of downloading the sources, check out the latest development release from the python dev repository every so often:
```
svn checkout http://svn.python.org/projects/python/branches/py3k
```
This will give you the very latest development, unstable, version. you can then cd py3k/ and do the above compilation procedure.

For this, svn needs to be installed of course.

Ubuntu – Making python 3.3 default python 3 interpreter instead of 3.2

You can custom your python3 alias. For this, you can modify your .bashrc file by appending "alias python3='python3.3'" at the end of it. This shell script can do it for you :

#!/bin/bash

cd ~

# Create the ~/.bashrc file if it does not exist
if [ ! -f ./.bashrc ]; then
    touch .bashrc
    chmod 755 .bashrc
    echo "#!/bin/bash" >> .bashrc
fi

# Append the customed alias
echo " " >> .bashrc
echo "alias python3='python3.3'" >> .bashrc
echo " " >> .bashrc

# Reload settings in the .bashrc script
source .bashrc
