Summing multiple values of each key in a dict?

Question

I have a python dictionary, which looks like this.

{ \'item1\' : [1,2,3,4,5,6],
  \'item2\' : [2,3,1],
   .
   .
   .
  \'item n\' : [4,2,4,3,2]
}

Answer 1

items = {'item1' : [1,2,3,4,5,6],
  'item2' : [2,3,1],
  'item3' : [4,2,4,3,2]
}

for key, values in items.items():
    items[key] = sum(values)
