Join txt files side by side in python
<p>I have 2 arrays of data in txt files:</p>

<blockquote>
  <p>A1 A2 A3<br>
  A4 A5 A6<br>
  A7 A8 A9</p>
</blockquote>

<p>and</p>

<blockquote>
  <p>B1 B2 B3<br>
  B4 B5 B6<br>
  B7 B8 B9</p>
</blockquote>

<p>I would like to combine them side by side:</p>

<blockquote>
  <p>A1 A2 A3 B1 B2 B3<br>
  A4 A5 A6 B4 B5 B6<br>
  A7 A8 A9 B7 B8 B9  </p>
</blockquote>

<p>(The spaces are actually tabs in my txt files)</p>

<p>Thank you!</p>
