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

Please help! String formatting with dictionaries

Hi, this code runs perfect in my computer but in treehouse I keep getting Bummer! dont understand why!!!

dicts = [{"name": "Michelangelo", "food": "PIZZA"}, {"name": "Garfield", "food": "lasagna"}]
template = "Hi, I'm {name} and I love to eat {food}!"

def string_factory(dicts, template): 
    new_list = []
    for names_and_food in dicts:
        new_template = template.format(**names_and_food)
    print (new_list)

string_factory (dicts, template)

OK, a few issues here.

First, they want you to return the list, not print it.

Second, don't put templates as an argument into the function. It can just grab the value from the templates variable, which will work fine.

Third, you don't need to call the function, just define it.

Finally, in the format part of the function, the placeholder name must be given a value to fill in. Set name equal to the dict item name and set food equal to the dict item food.

Here is the code for the function prewritten so you don't have to do all this yourself.

def string_factory(dicts): 
    new_list = []
    for name_and_food in dicts:
        new_template = template.format(name=name_and_food["name"], food=name_and_food["food"])
    return new_list

The dictionary and template definitions, you can keep in there.

many thanks Zack!! that makes a lot of sense!

You are welcome.

:x: Actually Python doesn't care about spaces between function names and parameters (as long as the arguments are wrapped in parentheses).

Thanks for the comment Alexander, but given this was a treehouse challenge, I felt it might be something that would stop the task passing, keep up the good work
