Test if it worked: /opt/python3.3/bin/python3 Sudo apt-get install libreadline-dev libncurses5-dev libssl1.0.0 tk8.5-dev zlib1g-dev liblzma-dev Install dependencies: sudo apt-get build-dep python3.2 Here is what I did to install Python 3.3 on Ubuntu 12.04:

Its goal is to help you manage multiple Python versions. There's a software called pyenv which may help you to automate the procedure - what it essentially does is compile Python from source, installing it in your home directory. Now you can have any Python version, even an alpha, or, say, to have a few copies of Python 3.3 compiled with different settings. Ln -s /opt/python3.3/bin/python3.3 ~/bin/pyĪlternatively, you can install a bash alias named py instead: echo 'alias py='/opt/python3.3/bin/python3.3'' >. Some nice touches to install a py command by creating a symlink: mkdir ~/bin Sudo apt-get install sqlite3 # for the command-line client SQLite libs need to be installed in order for Python to have SQLite support. We need C compiler and other stuff to compile Python sudo apt-get install build-essential On my dev machine I have literally dozens of different Python versions from 2.4 to 3.2 living happily in /opt.

This is very easy and allows you to have multiple Python versions without messing with system python interpreter (which is used by a lot of Ubuntu own programs).
