title: How to get particular Column of DataFrame in pandas?
body: <p>I have a data frame name it <strong>df</strong> I want to have like its first and second colums(series) in variable <strong>x</strong> and <strong>y</strong>.</p>
  
  <p>I would have done that by name of the column like <code>df['A']</code> or <code>df['B']</code> or something like that.</p>
  
  <p>But problem here is that data is itself header and it has no name.Header is like 2.17 ,3.145 like that.</p>
  
  <p>So my Question is:</p>
  
  <p>a) How to name column and start the data(which starts now from head) right after the name ?</p>
  
  <p>b) How to get particular column's data if we don't know the name or it doesn't have the name ?</p>
  
  <p><strong>Thank you.</strong></p>
