Python Python Collections (2016, retired 2019) Dictionaries String Formatting with Dictionaries

Unpacking a list of dictionaries

You've used the string .format() method before to fill in blank placeholders. If you use a placeholder of {food} in the string, then you pass a keyword argument of food to .format(). The {food} placeholder in the string will be replaced with the value of the food keyword argument.

"Hi, I'm {name} and I love to eat {food}!".format(name="Kenneth", food="tacos")

Returns "Hi, I'm Kenneth and I love to eat tacos!"

Complete the favorite_food function below. It accepts a dictionary as an argument. Your function should unpack that dictionary and pass it to the format method as keywords, then return the resulting string.

I've tried every possible ways I could think of, but it just won't work for me. I keep getting an error message that the argument after ** should be a mapping not str. However, I am able to pass this code on my workplace console. What is going on here? Please help.

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

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

def favorite_food(dicts):
    new_list = []
    for item in dicts:
    return new_list

Hi Sean. In this quiz only 6 characters is needed, nothing more. You changed the original code. Inside the format you just unpack the dict


and that passes. Happy coding
