title: pylint, pandas : Comparison to True should be just 'expr' or 'expr is True' (singleton-comparison)
body: <p>did anyone solve this pylint issue when using pandas?</p>
  
  <pre><code>C:525,59: Comparison to True should be just 'expr' or 'expr is True' (singleton-comparison)
  </code></pre>
  
  <p>this happens in the line where i'm using:</p>
  
  <pre><code>df_current_dayparts_raw['is_standard'] == True
  </code></pre>
  
  <p>I tried these but didn't work:</p>
  
  <pre><code>df_current_dayparts_raw['is_standard'] is True
  df_current_dayparts_raw['is_standard'].isin([True])
  df_current_dayparts_raw['is_standard'].__eq__(True)
  </code></pre>
