strings.py solution

I made a solution which works in my workspace, but in the tool it's complaining about the update sequence being 1, while it should be 2. Beats 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, dicts):
  new_list_of_strings = []
  count = 0
  for item in dicts:
    dicts_sub = dict(dicts[count])
    new_list_of_strings.append(string.format(**dicts_sub))
    count += 1

  return(new_list_of_strings)

Your parameter order matters. The task says "Create a function named string_factory that accepts a list of dictionaries and a string" in that order.

Your code for iterating the list of dicts is unusual. 

  for item in dicts:
    dicts_sub = dict(dicts[count])

The for-loop assigns to item each dict listed in dicts and it can be used directly in place of dicts_sub

  for item in dicts:
      new_list_of_strings.append(string.format(**item))

Hi Chris, thanks! I introduced the dicts_sub, because item directly seemed not to work eighter (but probably I did somwthing else wrong... :-) ).
