Code Challenge String Formatting with Dictionaries

dicts = [ {'name': 'Michelangelo', 'food': 'PIZZA'}, {'name': 'Garfield', 'food': 'lasanga'}, ]

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

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

So this was the answer that I used to get through the challenge and admittedly I used help from the forums to complete it. However, could someone take the time to explain what exactly is happening, having a hard time grasping this one. I get everything up until what is actually happening in the 'string_list.append(string.format(**dict))' part.

Thanks for any help.

I would recommend re-watching the video.

Anyway, this:

a = {
  'name': 'Alex',
  'age': 1000,
  'language': 'English',
  'programming_lang': 'Python'

fmt = """My name is {name} and I am {age} years old.
I speak {language} and I code in {programming_lang}."""


Is the same thing as this:

fmt = """My name is {name} and I am {age} years old.
I speak {language} and I code in {programming_lang}."""
