How to do partial carriage return
<p>I want to replace the cmd output of my Python script, without overwriting the first three characters of the line. Here is what I mean:</p>

<p>How I want it:</p>

<pre><code>&gt;&gt;&gt;ID1 downloading
&gt;&gt;&gt;ID1 converting
&gt;&gt;&gt;ID1 finished
</code></pre>

<p>With <code>/r</code>:</p>

<pre><code>&gt;&gt;&gt;ID0 downloading
&gt;&gt;&gt;converting
&gt;&gt;&gt;finished
</code></pre>
