title: Exclude one or more items from pandas Series
body: <p>I am wondering how to exclude one or more items from the pandas series. For example:</p>
  
  <pre><code>s = pd.Series(data=range(10), index=[chr(ord('A') + x) for x in range(10)])
  </code></pre>
  
  <p>Now I want to exclude rows B, D, E</p>
  
  <p>An extremely inefficient way is to do this:</p>
  
  <pre><code>index = s.index
  for col in ['B','D','E']:
      index = index.delete(index.get_loc(col))
  
  new_series = s[index]
  </code></pre>
  
  <p>Is there any better way to do this?</p>
  
  <p>Thanks. </p>
