hi, I have checked my work in the work space, why dose the strings split to letters? or what is the correct code?

what is the correct code?

strings.py 
dicts = [
    {'name': 'Michelangelo',
     'food': 'PIZZA'},
    {'name': 'Garfield',
     'food': 'lasanga'},
    {'name': 'Walter',
     'food': 'pancakes'},
    {'name': 'Galactus',
     'food': 'worlds'}
]

string = "Hi, I'm {name} and I love to eat {food}!"

def string_factory(dicts,string):
  new_list=[]
  for item in dicts:
    new_list.extend(string.format(**item))
  return new_list

extend will iterate through the collection passed in, adding each element as a separate item (each character in this case). append is what you're looking for, it will add whatever you pass to it as it's own element.
