title: Extract data from tsv file python
body: <p>I have a TSV file, that looks like this:</p>
  
  <pre><code>A   B   C   D   D=1;E=2
  S   D   F   G   H=2;B=4
  </code></pre>
  
  <p>I'd like to write the contents to another tsv file in this way. </p>
  
  <pre><code>A   B   C   D   D   1
  A   B   C   D   E   2
  S   D   F   G   H   2
  S   D   F   G   B   4
  </code></pre>
  
  <p>I'd really appreciate if anyone could help/ hint me in splitting column 5 as desired. </p>
