title: how to drop a range of columns in pandas?
body: <p>I have a very large dataframe with 108 columns and 8000 rows, and I want to drop some of the columns.
  It doesn't have a specific column name, it only has index on as column name.</p>
  <p>the columns I want to remove is from 74 to 104.</p>
  <p>I have tried:</p>
  <pre><code>df.drop(['74', '104'], axis = 1, inplace = True)
  </code></pre>
  <p>but it said:</p>
  <pre><code>['74' '104'] not found in axis
  </code></pre>
  <p>which 74 and 104 are the column index I want to remove.</p>
  <p>How can I fix this problem?</p>
  <p>Thank you in advance</p>
