title: Updating Python 3.4x to 3.5
body: <p>just a quick question. I have Python 2.7 on my mac by default. I have also installed 3.4 and use it more than 2.7, but would like to upgrade to the new 3.5. Should I remove 3.4 and just lay down a new install of 3.5, or is there a way to just update it. All my searches just talk about upgrading from 2.7 to 3x. I am just concerned about messing one of the installs up. Any input would be greatly appreciated.
  Cheers.</p>
