I need help with this challenge

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.

this is the code: def favorite_food(dict): return "Hi, I'm {name} and I love to eat {food}!".format() I don't know what to add or do, could someone help me?

string_factory.py 
def favorite_food(**dict):
    return "Hi, I'm {name} and I love to eat {food}!".format(dict[name], dict[food])

Hi Natalia, try to unpack the dict inside the format method using the **. You don't need to unpack dict in the method declaration.

Or you can modify your code and assign key and value to name and food "variables" like this:

def favorite_food(dict): 
    return "Hi, I'm {name} and I love to eat {food}!".format(name=dict['name'], food=dict['food'])

Does it make sense?

You have the right idea, just the **dict is in the wrong place (you don't need it in the function argument but somewhere else!)
