In your code, "dicts" is a list of dictionaries. Ultimately, it is a list. You cannot use ** on a list. You need to take the dictionaries out of the list and apply them to your string iteratively. Please see the modified code below. 

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):
    string_list = []
    for item in dicts:
        string_list.append(string.format(**item))

    return string_list

print(string_factory(dicts,string))

Since the question asks for just one function parameter the answer from >Keerthi Suria Kumar Arumugam can be converted to that:

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

def string_factory(values):
    output_string = []
    for d in values:
        output_string.append(template.format(**d))
    return output_string
