title: What is the best way to iterate over multiple lists at once?
body: <p>Let's say I have two or more lists of same length. What's a good way to iterate through them?</p>
  
  <p><code>a</code>, <code>b</code> are the lists.</p>
  
  <pre><code> for i, ele in enumerate(a):
      print ele, b[i]
  </code></pre>
  
  <p>or</p>
  
  <pre><code>for i in range(len(a)):
     print a[i], b[i]
  </code></pre>
  
  <p>or is there any variant I am missing?</p>
  
  <p>Is there any particular advantages of using one over other?</p>
