title: python3 loading dist-packages from python2 on ubuntu
body: <p>I have fresh ubuntu 16.04 setup for production.
  Initially if when i type<br>
  <code>python --version</code> gives me <code>python 2.7</code> and <code>python3 --version</code> gives me <code>python 3.5</code><br>
  but i want <code>python</code> points to <code>python3</code> by default, so in my <code>~/.bashrc</code><br>
  <code>alias python=python3</code> and <code>source ~/.bashrc</code>,<br>
  After that i install <code>pip</code> using <code>sudo apt-get install python-pip</code> and when i type <code>pip --version</code> it prints <code>pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)</code> instead that i want packages to be installed into and get from <code>/usr/local/lib/python3.5/dist-packages</code>.
  I have django application which is written with python3 compatible code. </p>
  
  <p><strong>Update:</strong>  I want to install other packages which have to load from <code>python3 dist-packages</code> not just <code>pip</code>. I don't want to remove <code>python 2.7</code> from ubuntu it will break other programs, i thought <code>alias python=python3</code> would install packages into python3.5 dist-packages as well.</p>
