title: Is there a pandas filter that allows any value?
body: <p>Is there a pandas filter that allows any value?</p>
  
  <pre><code>df[df['column'] == ANYTHING]
  </code></pre>
  
  <p>Basically I'm building a bokeh plot with widgets to filter a dataframe but I don't want to add a "No filter" option in my dataframe because it would become really large if I would do that. </p>
