Create a function named string_factory that accepts a list of dictionaries and a string.

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):
  strings = []
  for item in dicts:
    string.format(**dicts)
    strings.append(string)
  return strings

I watched the video am following it with the **, but the output will not come out correctly..

Your code is fine with one small exception.

Calling str.format() doesn't change the string, it makes a new string, so you need it to be assigned to a variable (or just put that straight into strings.append()).

Hi David,

I actually asked the same question about a month ago as I was completely stuck. Tried to solve it this morning and was still stuck actually, had to look at the answer again :).

First of all it would be great if you could indent and format the code using the Markdown Cheatsheet below so that the code is readable.

Potential solution:

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

I think that should work.
