title: Combine lists row-wise (Python)
body: <p>Let's say I have 3 different lists</p>
  
  <pre><code>col1 = ['2006-03-28','2006-04-05','2006-04-06']
  col2 = ['IBM', 'MSFT', 'IBM']
  col3 = [1000, 1000, 500]
  </code></pre>
  
  <p>What is the most efficient way to combine those lists in another list like this: </p>
  
  <pre><code>col = [('2006-03-28', 'IBM', 1000),
         ('2006-04-05', 'MSFT', 1000),
         ('2006-04-06', 'IBM', 500)]
  </code></pre>
