title: Read csv file and split in columns keeping column names. Pandas
body: <p>When i import csv file with ";" separator and then split columns, they appear without original names but indexed.</p>
  
  <p>How to keep names when splitting columns? 
  I do it with the following code: (the test file can be found <a href="https://github.com/veronique-ka/tests/blob/master/test.csv" rel="nofollow noreferrer">here</a></p>
  
  <pre><code>data= pd.read_csv('path')
  data=data.iloc[:,0]
  data = data.str.split(';', expand=True)
  </code></pre>
  
  <p>i just simply rename them but I wonder if it's possible to keep them as they are. Thank you</p>
