title: How to display some text before a value from a Dash callback?
body: <p>Using Plotly Dash, I have line <code>html.H6(id='output_div')</code> that displays an integer (say 10).</p>
  <p>I would like to display some text before that integer (say &quot;This is integer&quot;). I can’t use <code>{}.format()</code> in the callback function because I need to input that integer in another callback function.</p>
  <p>How could I modify <code>html.H6(id='output_div')</code> to display &quot;This is integer 10&quot; on a single line instead of &quot;10&quot;?</p>
