<pre><code>import IPython; IPython.embed()
</code></pre>
<p><code>IPython.embed()</code> starts an IPython shell which have access to the local variables from the point where you call it. </p>

<p>You can leverage <strong>nosetests</strong> and <strong>pdb</strong> together, rather injecting <code>pdb.set_trace()</code> in your views manually. The advantage is that you can observe error conditions when they first start, potentially in 3rd party code.</p>

Im trying to engineer in python a way of transforming a list of integer values between 0-255 into representative equivalent tones from 1500-2200Hz.
