<p>This implements polynomial functions over a single variable in Python. It represents the polynomial as a list of numbers and allows most arithmetic operations, using conventional Python syntax. It does not do symbolic manipulations. Instead, you can do things like this:</p>
<pre class="prettyprint"><code>x = SimplePolynomial()
eq = (x-1)*(x*1)
print eq # prints 'X**2 - 1'
print eq(4) # prints 15
</code></pre>
