title: numpy iterating over multidimensional array
body: <p>I am very new to numpy and I am trying to achieve the following in the most pythonic way. So, I have two arrays:</p>
  
  <pre><code>a=array([[0, 1, 2],[3,4,5]])
  b=zeros(a.shape)
  </code></pre>
  
  <p>Now, what I would like is for each element in b for be one greater than the value of the corresponding element in a i.e b=a+1</p>
  
  <p>I was wondering how this can be achieved in numpy.</p>
