title: Printing 2D-array in a grid
body: <p>I need to print this to look like:</p>
  
  <pre><code>....
  
  ....
  
  ....
  </code></pre>
  
  <p>currently I have this:</p>
  
  <pre><code>def main():
      rows=3
      col=4
      values=[[0,0,0,0],
              [0,0,0,0],
              [0,0,0,0]]
      for i in range(rows):
          for j in range(col):
              values[i][j]='.'
      print(values)
  main()
  </code></pre>
  
  <p>which will print
  [['.', '.', '.', '.'], ['.', '.', '.', '.'], ['.', '.', '.', '.']]</p>
  
  <p>Is there a way to get it looking nicer?</p>
