title: How do I format numeric values in a Panel widget?
body: <p>Using the <a href="https://panel.holoviz.org/" rel="nofollow noreferrer">Python library Panel</a>, I'm trying to format an IntSliderRange to <code>f&quot;{the_slider_number} kr&quot;</code> but the formatting argument in that class is not doing anything with the python text formatting tricks I am familiar with: 'kr', '{} kr', '{0} kr', etc.</p>
  <p>Running <code>help(pn.widgets.IntRangeSlider)</code> tells me that I have to provide &quot;A format string or bokeh TickFormatter&quot; but I can't seem to find any relevant search results based on that.</p>
  <p>Copilot suggests '0[.]0a' as an argument which does stuff to the format, namely express the numbers in thousands (1234 -&gt; &quot;1.2k&quot;), but that's not at all what I want.</p>
  <p>Does anyone recognize this formatting system? Where can I find out how to use it?</p>
