Python Python Collections (Retired) Dictionaries String Formatting with Dictionaries

How do I get the function to unpack a list of dictionaries into the same string and return it?

I'm stuck on the code challenge for unpacking a list of dictionaries.

I feel like I need to create some sort of loop that returns the string with the different dictionaries unpacked into it, but I'm completely stumped on how to do this. Help?

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(dicts, string):
  dicts.split() = dicts_li
  for dict in dicts_li:
    return string.format(**dict)

Hi Megan,

You're on the right track but have some invalid code.

  1. dicts.split() = dicts_li is invalid and isn't required as we aren't splitting a string
  2. You're returning from within the for loop which is where you should be appending the formatted string into an array

See the below example, I've created a new array called formatted and am appending each formatted order onto it and returning the array once the loop is complete.

def string_factory(orders, format_string):
  formatted = []

  for order in orders:
    formatted.append(format_string.format(**order))

  return formatted

Happy coding!
