title: How to uninstall Python 3.4 from Mac OS X?
body: <p>I have python 2.7.9 installed by default on my mac. I then installed python 3.4.2. Later after some time, without realizing I also installed python 3.5.1. Now I have three python versions in my machine. I would like to uninstall python 3.4.1 as I have no use for it. Do you recommend doing this or should I leave it as it is? I installed everything from <a href="http://www.python.org/" rel="noreferrer">http://www.python.org/</a>
  Do I also need to change some path variables? And what will be my default python version?</p>
  
  <p>OSX 10.11</p>
