Python Python Collections (Retired) Dictionaries String Formatting with Dictionaries

if I print out the formatted string it looks correct. But the return only prints the last line. 

def string_factory(dicts, string):

    index = 0
    for item in dicts:
        build_string = []
        # build_string = string.format(**dicts[index])
        build_string.append(string.format(**dicts[index]))
        print(build_string)
        index +=1
    return build_string

Hi John,

You are very close to the solution. You were passing the list of dictionaries as arguments to 'format' instead of single item from the list.Here is the bit you need to change in your code. 

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}!"
build_string=[]

def string_factory(dicts, string):
    for item in dicts:
        build_string.append(string.format(**item))
    return build_string

Thanks Manickaraja, I'll take a look at that.
