Upgrade python 3.4 to 3.5 (latest) in ubuntu 14.04
<p>How to upgrade Python 3.4 to the latest version available on ubuntu 14.04</p>

<p>I would recommend adding an additional installation and not actually upgrading the <code>python3</code> binary past where ubuntu expects it. Anything system use of python that depends on python3.4 but breaks under 3.5, will make your life tough.</p>

<p><a href="https://github.com/yyuu/pyenv" rel="nofollow">pyenv</a> is nice tool for maintaining multiple local versions of python but it'll almost certainly replace virtualenv in your workflow.</p>
