title: Problems setting up Python
body: <p>I recently installed python 3.3.2 
  Im trying to install NumPy, when I call import NumPy from the command line I get the following error: </p>
  
  <pre><code>import numpy
  Traceback (most recent call last):
    File "&lt;console&gt;", line 1, in &lt;module&gt;
  ImportError: No module named 'numpy'
  </code></pre>
  
  <p>From what I've read it may have to do with having multiple version of Python installed.
  The only problem is when I try run the Which Python command I get another error?</p>
  
  <pre><code>which python
    File "&lt;console&gt;", line 1
      which python
                 ^
  SyntaxError: invalid syntax
  </code></pre>
