title: Getting a single list from a 2D list in Python 3.x?
body: <p>Having some difficulty here. My goal is to read numbers from a column in a gameboard and print these numbers out as a specific list. I don't have much experience with lists and neither do I grasp the concept properly so I'm having some difficulty with getting them to work. So far, all I could muster was this:</p>
  
  <pre><code>def getColumn ():
      for i in range (0, 9):
          row = datalist[i]
          column = row[x]
          column.append[i]
  </code></pre>
  
  <p>Doesn't seem to work properly, could anyone point out why? I would really appreciate it!</p>
  
  <p>Thanks!</p>
