title: removing known outliers from pandas dataframe
body: <p>In a pandas dataframe subsets (here my outliers) should be removed:</p>
  
  <p>example:</p>
  
  <pre><code>df = data[~(data.outlier1 == 1)]
  </code></pre>
  
  <p>But my dataframe has multiple outlier rows.</p>
  
  <p>Is there something like:</p>
  
  <pre><code> df = data[~((data.outlier1 == 1) or (data.outlier2 == 1) or (data.outlier3 == 1))]
  </code></pre>
  
  <p>The idea is to subtract all outliers (encoded in different rows) at the same time.</p>
