title: Pythonic way to print 2D list -- Python
body: <p>I have a 2D list of characters in this fashion:</p>
  
  <pre><code>a = [['1','2','3'],
       ['4','5','6'],
       ['7','8','9']]
  </code></pre>
  
  <p>What's the most pythonic way to print the list as a whole block? I.e. no commas or brackets:</p>
  
  <pre><code>123
  456
  789
  </code></pre>
