Create a function named string_factory that accepts a list of dictionaries and a string. Return a new list build by usin

As the title says i have to :

Create a function named string_factory that accepts a list of dictionaries and a string. Return a new list build by using .format() on the string, filled in by each of the dictionaries in the list.

My code's down below but hm i can't figure it out :p Hope you can help me

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

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

def string_factory(string, string):
  for dicts in string:
    return string.format(**dicts)

Here's a few hints:

  • you can't use the same argument name twice in a function definition (how could you tell them apart later?)
  • you need to build a new list inside the loop (don't return)
  • when you do return after the loop, pass back the newly-created list

If you're still stuck, here's how I did it:

:warning: SPOILER ALERT

def string_factory(dicts, string):
  newlist = []
  for each in dicts:
    newlist.append(string.format(name=each['name'], food=each['food']))
  return newlist

Though I have to say, string_list.append(string.format(**dict)) is a bit more in keeping with the video lesson just prior to the challenge. :+1:

That's a much better format for giving out help. I'll have to keep it in mind. Much less "SNAPE KILLS TRINITY WITH ROSEBUD!" than my answer was. (:

You're getting there. You formatted the string correctly, though! You can't call both your arguments "string". Also, you're suppose to put all the formatted strings in a list, and then return that list.

def string_factory(dicts, string):
    string_list = []
    for dict in dicts:
        string_list.append(string.format(**dict))
    return string_list

I hope this helps!
