title: When reading csv file with pandas, can I select the column to import when there is not column name?
body: <p>I have a long dataset to import into pandas. I only need the first X columns but these columns have no header. Can I select the first (e.g. 5 columns) and ignore the rest and then add the column's name to these 5 columns?</p>
  <p>I could import the full dataset and do the selection later but it is a bit low to import the full dataset.</p>
