Hello Linux Geeksters. As you may know, Python 3.3.5 has been released last month, coming with a bunch of fixes for some critical issues on the previous Python version. For information about this release, see the changelog.
In this article I will show you how to install Python 3.3.5 on Ubuntu 14.04 Trusty Tahr, Ubuntu 12.04 Precise Pangolin, Linux Mint 17 Qiana, Linux Mint 13 Maya, Pinguy OS 14.04, Pinguy OS 12.04, Elementary OS 0.3 Isis and Elementary OS 0.2 Luna.
Because it is available via PPA, installing Python 3.3.5 on the listed Ubuntu, Linux Mint, Elementary OS and Pinguy OS systems is easy. All you have to do is add the ppa to your system, update the local repository index and install the python3.3 package. Like this:
$ sudo add-apt-repository ppa:fkrull/deadsnakes
$ sudo apt-get update
$ sudo apt-get install python3.3
The easiest way to make Python 3.3 as default is to symlink it:
$ rm /usr/local/bin/python
$ ln -s /usr/bin/python3.3 /usr/bin/python
Optional, to remove Python 3.3, do:
$ sudo apt-get remove python3.3
