<p>If this is already a defined function within Python, please let me know--a quick web search turned up nothing.</p>

<p>It requires NOTHING special at all to work and can be run like above or imported from
the correct "Lib" drawer/folder/directorfy as:-</p>
<pre class="prettyprint"><code>>>> import d2b
</code></pre>
<p>And when imported called as:-</p>
<pre class="prettyprint"><code>>>> d2b.d2b(some_number, optional_some_other_mumber)<RETURN/ENTER>
</code></pre>
<p>OR</p>
<pre class="prettyprint"><code>>>> d2b.t2b(some_ASCII_string)<RETURN/ENTER>
</code></pre>
