'list' object has no attribute 'format'

In my IDE this code work,but in challange not,i don't understand why

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(in_str,some_dict):
  new_list=[]
  for val in some_dict:
    new_list.append(str(in_str.format(**val)))

  return new_list

As the prompt says (and shez azr said), the list of dictionaries comes first and the string comes second. Your IDE really doesn't have any say in this matter ;)

This was stumping me too; I made the same error. Treehouse's answer-checking script is expecting the inputs in a specific order ("...accepts a list of dictionaries and a string").

Well, yeah. :) All programming requires specific orders to things.

I found this one very challenging (I am a newbie but I watched the videos and research before asking for help.) This was my answer and it worked

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

What I didnt know was to do the fillin.append(string.format(**keys)) I found on stack overflow something similar and was able to grasp how to finish this challenge. Like I never knew I could use list.append(second_list.format()) a nice thing to know...
