most negative value for python
<p>I expect the most negative for python is <code>-maxint-1</code></p>

<p>I expect having -2, will make integer overflow.</p>

<pre><code>from sys import maxint
maximum_int = maxint
minimum_int = -maxint - 2
#  2147483647
# -2147483649
print maximum_int
print minimum_int
</code></pre>

<p>Yet. Correct result is displayed, and a value which is more negative than <code>-maxint-1</code> is shown.</p>

<p>May I know why?</p>
