title: Reshaping an array to 2-D by specifying only the column size
body: <p>I have a vector of length, lets say 10:</p>
  
  <pre><code>foo = np.arange(2,12)
  </code></pre>
  
  <p>In order to convert it to a 2-D array, with lets say 2 columns, I use the command <code>reshape</code> with following arguments:</p>
  
  <pre><code>foo.reshape(len(foo)/2, 2)
  </code></pre>
  
  <p>I was wondering if there is a more elegant way/syntax to do that (may be sth like <code>foo.reshape(,2)</code> ) </p>
