title: Remove character from dictionary values
body: <p>I am sure this is quite elementary, however I haven't found a similar question.
  I have a dictionary:</p>
  
  <pre><code>tenants = {'John': ['Address1\r'], 'Claudia': ['Address2\r'], 'Mike': ['Address3\r']}
  </code></pre>
  
  <p>How can I remove the "\r" in the values?</p>
