title: Replace single digit with 'space and digit' Python ex: ASSESSMENT _2/28
body: <pre><code>DF_Column:         ASSESSMENT
              ASSESSMENT 21/28, MISSED
              ASSESSMENT 1/28, MISSED
              ASSESSMENT 2/28, MISSED
              ASSESSMENT 23/28, MISSED
              ASSESSMENT 23/28, MISSED
              ASSESSMENT 5/28, MISSED
  </code></pre>
  <p>What I want in python:</p>
  <pre><code>               ASSESSMENT
          ASSESSMENT 21/28, MISSED
          ASSESSMENT  1/28, MISSED
          ASSESSMENT  2/28, MISSED
          ASSESSMENT 23/28, MISSED
          ASSESSMENT 23/28, MISSED
          ASSESSMENT  5/28, MISSED
  </code></pre>
  <p>There should be double space after ASSESSMENT if it is singleDigit/28</p>
