title: "Command not found" error after installing Python 3.3 on OS X
body: <p>I was using Python 2.7 as it was installed on my Mac by default. I tried to update it to python 3.4. In the process I deleted 2.7 via the command line. 
  I installed python 3.4 using an installer but I am still getting following error:</p>
  
  <blockquote>
    <p>python: Command not found</p>
  </blockquote>
  
  <p>I checked and found that this folder does not exist:</p>
  
  <blockquote>
    <p>/Library/Frameworks/Python.framework/Versions/3.4</p>
  </blockquote>
  
  <p>I followed the instructions on <a href="http://wolfpaulus.com/jounal/mac/installing_python_osx/" rel="nofollow">this website</a> to update Python. Everything went well until step 5 but was unsuccessful for step 6 and 7.</p>
  
  <p>I am in a complete mess as I have deleted the older version, Python 2.7. How can I fix my Python installation to solve the error and use Python 3.4?</p>
