Help please?

I did the excercise but is not working, treehouse is telling me that "argument after ** must be a mapping, not list" I don't know what to do

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):
    return string.format(**dicts)

It's asking for a list not a string. The challenge is quite confusing though. Here is my solution:

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(dlist, s): new = []

for d in dlist:
    new.append(s.format(**d))

return new

For some reason the syntax highlighting isn't working...
