title: python read exel file error beginning zeros error
body: <p>I have a  Excel file 'test.xls' file which I could read in as following:</p>
  
  <pre><code>    df=  pd.read_excel('test.xls',sep='\t',header=1)
  </code></pre>
  
  <p>I checked df and found there is a  column  zip_code which contain zip code like 00051, 00123, but the first 0 was  cut off  while the system  read in the excel file. </p>
  
  <p>So  that column will be 51, 123. How could I keep the first zeros intact while reading the file. Thanks.
  Found solution as I posted  below.</p>
