title: I don't know how to update my Python version to 3.4?
body: <p>I'm on OSX, and I installed IDLE for Python 3.4. However, in Terminal my <code>python -V</code> and <code>pip --version</code> are both Python 2.7. </p>
  
  <p>How do I fix this? I really have no idea how any of this works, so please bear with my lack of knowledge.</p>
