What do these lines of code do?
<p>I am working with <code>numpy</code>. I encountered this line of code. </p>

<pre><code>a = (1.,80.,5.)
</code></pre>

<p>What does this mean? At some other line, I found</p>

<pre><code>aList = np.arange(a[0], a[1]+a[2], a[2])
</code></pre>

<p><strong>Note:</strong> <code>np</code> is namespace assigned from <code>numpy</code>.</p>

<p>First line is just a tuple.</p>

<p>Second line is using the <code>np.arange</code> method which returns venly spaced values within a given interval:</p>

<p><code>np.arange(start, stop, step)</code></p>

<p>The parameters you have are using the tuple, <code>a</code>.
Where <code>a[0] = 1</code> and <code>a[1] = 80</code> so on...</p>
