Download the 3.4.2 source files from here
Extract it to a temporary directory within your Downloads folder
Open a terminal session.
Navigate to the folder with cd ~/Downloads/Python-3.4.2
As per the Python documentation, run the following commands from the terminal:
```
./configure
make
make test
sudo make install
```

This will upgrade your existing Python-3.4 installation to Python-3.4.2 (accessible as python3)

Do not to forget to: sudo apt-get build-dep python3.4 before make install or pyenv install, or you will be missing built-in modules like readline, sqlite3, etc. – eddygeek Jan 05 '15 at 21:24

You can also use pyenv as your python manager. pyenv

It will allow you to install any version of python, pypy, python3, stackless etc.

it uses shims and also has a nice plugin for virtualenv which makes it a very easy option to use pyenv-virtualenv

Very simple installation.

curl -L https://raw.githubusercontent.com/yyuu/pyenv-installer/master/bin/pyenv-installer | bash

find out which versions are available to install

$ pyenv install --list

install python 3.4.2

The package pyenv doesn't seem to be in the repository... – Mario S. E. Oct 20 '14 at 21:36
@MarioS.E. you install it into your home directory: http://opencafe.readthedocs.org/en/latest/getting_started/pyenv/ – Doug T. Dec 24 '14 at 16:28
I have lost all my installed packages after using pyenv. Is there a way to map my old dist-packages to the new python? – alvas Jan 05 '16 at 12:22

trusty-updates release channel of Ubuntu 14.04 LTS provides Python 3.4.3 (if you want simply newer version of Python than 3.4.0, not exactly 3.4.2).

You can enable trusty-updates in Software & Updates settings (they should be enabled by default):
