Python 3.5 Extract Digits from Column into New Column : <p>I am trying to extract the last 5 digits of a number in a columun in a CSV and add it as an additional column.  There are more columns in my actual data, and there are thousands of rows of numbers.  For example:</p>

<pre><code>Column 1, Column 2, Column 3, Column 4
3333333, 1234567, 4444444, 5555555
7777777, 7654321, 5555555, 6666666
</code></pre>

<p>and I want it to be:</p>

<pre><code>   Column 1, Column 2, Column 3, Column 4, Column 5
   33333333, 1234567,  44444444, 55555555, 34567
   77777777, 7654321,  55555555, 66666666, 54321
</code></pre>

<p>So far I have tried iterations of findall and think that regex is going to provide the best solution.  I can extract the column, not exactly what I want to do, but so far that is as far as I have gotten.</p>
