Insert tabs with .join in python
<p>This is probably basic, but I can't find a solution.  I have a string, e.g.,</p>

<pre><code>s = 'a,b,c,d'
</code></pre>

<p>I'd like to convert the commas to tabs.  But using .replace, e.g.,</p>

<pre><code>s.replace(',', '\t')
</code></pre>

<p>gives me </p>

<pre><code>&gt;&gt;&gt; s.replace(',', '\t')
'a\tb\tc\td'
</code></pre>

<p>I also tried converting to a list and then adding the tabs with a .join, e.g.,</p>

<pre><code>'\t'.join(s.split(','))
</code></pre>

<p>but that gives the same result.  How can I have the tabs actually inserted as tabs?</p>
