title: How to assign values of one list to values of second list when their length is not equal?
body: <p>Input is:</p>
  <pre><code>B = [1,2,3,4,5,6,7]
  A = ['A','B','C']
  </code></pre>
  <p>Output should be:</p>
  <pre><code>C = {'A':[1,4,7], 'B':[2,5], 'C':[3,6]}
  </code></pre>
  <p>The length of lists are dynamic (not fixed) but length of list B is always going to be greater than length of list A.</p>
