Challenge need help

https://teamtreehouse.com/library/python-collections-2/dictionaries/string-formatting-with-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.

Here's my code..

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

And I keep getting this error.. Bummer! Expected favorite_food({'name': 'Michelangelo', 'food': 'PIZZA'}) to return "Hi, I'm Michelangelo and I love to eat PIZZA!", but got "Hi, I'm Victoria and I love to eat tacos!"

I tried switching the words to what they wanted and it didn't help, they just asked for a different sentence. I don't know what's going on here, it looks like my code is returning the line they're asking for?

Your code is basically correct. You just need to remove this line:

    dict = {"name": "Victoria", "food": "tacos"}

By setting the variable dict inside your function, you are overwriting whatever is passed in. You want your function to work for any appropriate dictionary which is passed in.

As an aside, using dict as a variable name isn't a good idea, since it is the name of a built-in type in Python. It does work for this challenge though.

Thanks, that worked. Looks like I was overthinking it.

Here's a simpler way based on the video.

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

Just use the ** (asterisk) to unpack your dictionary into those template.
