python find half time between two times
<p>I want to find half time between two times in python. Let's say I've two times </p>

<pre><code>start_time = '08:30:00'
end_time = '16:30:00'
</code></pre>

<p>If I want to display first half, it should print as<code>'08:30:00' and '12:30:00'</code>
If I want to display second half, it should print as <code>'12:30:00' and '16:30:00'</code></p>

<p>Any suggestions would be helpful.</p>
