title: Python Pandas: Sorting by multiple columns

  B     object

  D     object
  E     int32
  F     float64
  G     float64
  H     float64
  dtype: object
  </code></pre>
  
  <p>And I went to sort it using this code </p>
  
  <pre><code>df = df.sort_values(['C', 'E'], ascending=[0, 0])
  </code></pre>
  
  <p>and it sorted it by C correctly but not E at all. can anyone assist?</p>
