title: Reading columns of a txt file on python
body: <p>I am working with a .txt file. This has  100 rows and 5 columns. I need to divide it in five vectors of lenght 100, one for each column. I am trying to follow this: <a href="https://stackoverflow.com/questions/30216573/reading-specific-columns-from-a-text-file-in-python">Reading specific columns from a text file in python</a>. </p>
  
  <p>However, when I implement it as: </p>
  
  <pre><code>token = open('token_data.txt','r')
  linestoken=token.readlines()
  resulttoken=[]
  for x in linestoken:
      resulttoken.append(x.split(' ')[1])
  token.close()
  </code></pre>
  
  <p>I don't know how this is stored. If I write <code>print('resulttoken')</code>, nothing appears on my screen.</p>
  
  <p>Can someone please tell me what I am doing wrong?</p>
  
  <p>Thanks.
