title: Lists to columns of dataframe
body: <pre><code>df1 = pd.DataFrame(np.column_stack([CIK, period, data]), columns=['CIK','Period','Text'])
  </code></pre>
  
  <p>I have 3 lists which I want to be columns of my dataframe. Above code worked fine when my data was small. Now this gives me memory error. Am I missing something?
  Is there a different way to do this?</p>
