Code Challenge String Formatting with Dictionaries

Question

dicts = [
    {'name': 'Michelangelo',
     'food': 'PIZZA'},
    {'name': 'Garfield',
     'food': 'lasanga'},
]
string = "Hi, I'm {name} and I love to eat {food}!"
def stringfactory(dicts):
    stringlist = []
    for dict in dicts:
        stringlist.append(string.format(**dict))
    return stringlist
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:
```python
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}."""
print(fmt.format(**a))
```
Is the same thing as this:
```python
fmt = """My name is {name} and I am {age} years old.
I speak {language} and I code in {programming_lang}."""
print(fmt.format(name='Alex',
                 age=1000,
                 language='English',
                 programming_lang='Python'))
```
