title: join ordered items from multiple lists together to form new list of concatenated strings
body: <p>I have three lists that I'd like to concatenate such that the same items ordered in each list from each list join into one string. </p>
  
  <p>For example,
  I have a list of days, a list of months, and a list of years I'd like to combine in a new list such that I have one complete date but with '-' between the day-month and month-year. </p>
  
  <p>If day[0] = '15', month[0] = 'Mar' and year[0] = '2012', the date should look like this in the end '15-Mar-2012', etc. </p>
  
  <p>Using a list comprehension does not work as I just have iterations of combined dates for every item in each of the lists. Any help would be appreciated!</p>
  
  <pre><code>day = ['15', '09', '25', '03', '04', '05', '17', '14', '23', '20', '06', '19', '15', '04', '16', '22', '25', '08', '12', '18', '25', '15', '04', '24', '17', '13', '17', '18', '03', '23', '30', '22', '23', '16']
  month = ['Mar', 'Apr', 'Apr', 'May', 'Jun', 'Jun', 'Jul', 'Mar', 'Jul', 'Aug', 'Sep', 'Jun', 'Oct', 'Jan', 'Apr', 'Oct', 'Oct', 'Nov', 'Feb', 'Jun', 'Feb', 'Dec', 'May', 'Feb', 'Nov', 'Dec', 'Apr', 'Apr', 'Aug', 'May', 'May', 'Aug', 'May', 'May']
  year = ['2012', '2012', '2012', '2012', '2012', '2012', '2012', '2012', '2012', '2012', '2012', '2012', '2012', '2012', '2012', '2012', '2012', '2012', '2013', '2013', '2014', '2014', '2011', '2015', '2015', '2011', '2012', '2016', '2011', '2016', '2012', '2016', '2012', '2016']
  
  combined = [i + '-' + j + '-' + k for i in day for j in month for k in year]
