Sorting in python- How to sort in a different order? : <p>What is the python implementation to Sort this list: </p>

<pre><code>['a', 'C', 2, 'z', 'B', 1, 'h', 0, 'Y', 9]
</code></pre>

<p>into the below list?</p>

<pre><code>['a', 'B', 'C', 'h', 'Y', 'z', 9, 2, 1, 0]
</code></pre>

<p>Order: a->b->..->y->z->...3->-2->1->0</p>

<p>It is Case insensitive for letters ('A' is same as 'a').</p>

<p>Thank you!</p>
