im trying to run a mapper program to list a specific name item and how many item was made in each year. The "pair_list" object is a list of year, and item name(exp. ['2007', 240x240 box] , ['2009', 'Brokenwood Chardonnay'] ).
The result im expecting is something like:
2012 "Brokenwood Chardonnay" 23
2012 "Burgenham Beer" 12
2013 "Brokenwood Chardonnay" 80
2013 "300x300 container" 1023
