Full Stack JavaScript Techdegree Student 6,208 PointsUnpacking 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:
new_list.append(template.format(**item))
return new_list
print(favorite_food(dicts))

Treehouse Project ReviewerHi Sean. In this quiz only 6 characters is needed, nothing more. You changed the original code. Inside the format you just unpack the dict
.format(**dict)
and that passes. Happy coding
