title: Pandas Check Excel import for isnumeric() data in Dataframe
body: <p>I am importing data into Pandas from Excel and I need to verify that the data is numeric based on the Columns.  </p>
  
  <pre><code>        month      value        dp        wd  ...      mg   fee      pr      comment
  
  0  2013-07-31  208372.33   4206.84   4692.22  ...       0     0       0    some comment
  1  2013-08-31  210669.77      0.00   1270.28  ...       0     0       0        
  </code></pre>
  
  <p>There are about 20 columns and I only need to exclude the "month" and "comment" columns.</p>
  
  <p>Is there something like:  df.iloc[:, 2: 18].isnumeric() or will this require a loop?</p>
  
  <p>I would like to get a True / False response.</p>
  
  <p>thank you.</p>
