title: plot() in python error message: No module named 'plotting'
body: <p>I am trying to take an interesting course offered by Coursera on linear algebra. The course is in Python. I'm familiar with R instead.</p>
  
  <p>It seems like to follow the course I can't assume that plotting is going to be as easy as calling <code>plot()</code>.</p>
  
  <p>In particular, there is this command in one of the first lectures:</p>
  
  <pre><code>&gt;&gt;&gt;L = [2 + 2j, 3 + 2j, 1.75 + 1j]
  &gt;&gt;&gt;from plotting import plot
  &gt;&gt;&gt; plot(L)
  </code></pre>
  
  <p>which works fine for the instructor, but results in the following error when I try:</p>
  
  <pre><code>&gt;&gt;&gt; from plotting import plot
  Traceback (most recent call last):
    File "&lt;pyshell#4&gt;", line 1, in &lt;module&gt;
      from plotting import plot
  ImportError: No module named 'plotting'
  </code></pre>
  
  <p>I went to the help pages, and it mentions that plotting in Python uses the internet browser, and advising to check which browser is the default. I use Opera (don't ask...), and it seems as though it is one of the recognized browsers.</p>
  
  <p>If it is just a matter of installing the 'plotting' module as the error message clearly spells out, can I ask how this is done?</p>
  
  <p><strong>NOTE:</strong> I have circumvented this issue by simply downloading <a href="https://www.continuum.io/downloads" rel="nofollow noreferrer">anaconda</a> and then, from the <code>cmd</code> prompt calling <a href="http://ipython.org/notebook.html" rel="nofollow noreferrer">IP Notebook</a> typing: <code>&gt; ipython notebook</code> at the prompt. A browsers should open with the jupyter interface; ipython notebook is phenomenal, allowing scientific plotting, markdown and latex in a local webserver interface that is clean and nice. During the session the <code>cmd</code> windows should remain open. Also, to save projects to a folder, the directory should be changed to that folder before starting the session, also using the <code>cmd</code> line. This is what it looks like:</p>
