unpacking dictionary. i ran these results through idle and it works. why doesnt this pass on the website?

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

def string_factory(values):

    for i,item in enumerate(values):

        values[i] = template.format(**item)

    return values

print(string_factory([{"name": "Michelangelo", "food": "PIZZA"}, {"name": "Garfield", "food": "lasagna"}]))

string_factory.py 
# Example:
# values = [{"name": "Michelangelo", "food": "PIZZA"}, {"name": "Garfield", "food": "lasagna"}]
# string_factory(values)
# ["Hi, I'm Michelangelo and I love to eat PIZZA!", "Hi, I'm Garfield and I love to eat lasagna!"]

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

def string_factory(values):

    for i,item in enumerate(values):
        values[i] = template.format(**item)

    return(values)

Your code is good except that it modifies the input argument which seems to upset the checker. Tagging Kenneth Love to please check if modifying the input would cause a failure.

It's better to create a unique list, say, result then append the formatted strings to this list.
