title: why is my tab separation not working?
body: <p>I am trying to tab separate three variables as follows:</p>
  
  <pre><code>single_element = str(pos) + "\t" + str(ref) + "\t" +str(alt)
  </code></pre>
  
  <p>the output I get with <code>print(single_element)</code> is:</p>
  
  <pre><code>pos\tref\talt
  </code></pre>
  
  <p>but what I would like is:</p>
  
  <pre><code>pos    ref    alt
  </code></pre>
