title: How to acces a column in excel called '1 with python pandas
body: <p>I want to access a column in an excel file which is unfortunately called '1.</p>
  <p>I tried several ways of accessing this column but i now have the following:</p>
  <pre><code>filename_R000169    = glob(r'I:\kml\labs\molecdiagn\Dennis\Python\Vriezertemp\files\R000169*.xls') [0]
  R000169             = pd.read_excel (filename_R000169)
  R000169_delete_rows = R000169.drop([0,20])
  column_1            = R000169_delete_rows[str(1)].tolist()
  column_3            = R000169_delete_rows[str(3)].tolist()
  print(column_1)
  </code></pre>
  <p>The problem is that i keep getting a key error '1'.
  I also tried putting an escape character before it <code>\'1</code></p>
  <p>Does anyone has a simple solution for this?</p>
