title: Python3 puts a 'b' in front of date
body: <p>This Python 3 code:</p>
  
  <pre><code>commentmsg =   '\n' +  svn_date + ' Repo: '+ svn_repository  + ' Rev: ' + svn_revision  + ' User: ' + svn_author + '\n'
  </code></pre>
  
  <p>gives this result:</p>
  
  <pre><code>b'2020-01-29' b'09:26:49' Repo: SubversionTraining Rev: 478 User: bengt.nilsson
  </code></pre>
  
  <p>There is a 'b' in front of date and time, where does it come from and how do I get rid of it? 
  This started with Python 3. </p>
