title: How to handle the pylint message: Warning: Method could be a function
body: <p>I have a python class and ran pylint against it. One message it gave was:</p>
  
  <pre><code>Warning: Method could be a function
  </code></pre>
  
  <p>Is this telling me that it would be better to move this method out of the class because it doesn't use any instance variables? </p>
  
  <p>In C# I would make this a static method. What's the most pythonic thing to do here? </p>
