Having a hard time with Dictionary Challenge...

Hello all, MY code: template = "Hi, I'm {name} and I love to eat {food}!" value = [{"name": "Chris", "food": "pizza"}, {"name": "Del", "food": "peanuts"}]

def string_factory(value): new_list = [] for value in template: new_list.append(template.format(**value)) return new_list

Some of this code was taken from others as I could not for the life of me figure out this code. I created the two dictionaries in the the value variable. I then create the string_factory function with value as the argument. I felt creating a blank list for data dump was good. And ran the for loop which likely has syntactic errors.

I've re-watched the video 3 times. Does this stuff eventually click. I am basically lost in programming and can't seem to grasp it.

string_factory.py 
# Example:
# values = [{"name": "Michelangelo", "food": "PIZZA"}, {"name": "Garfield", "food": "lasagna"}]
# string_factory(values)
# ["Hi, I'm Michelangelo and I love to eat PIZZA!", "Hi, I'm Garfield and I love to eat lasagna!"]

template = "Hi, I'm {name} and I love to eat {food}!"
value = [{"name": "Chris", "food": "pizza"}, {"name": "Del", "food": "peanuts"}]

def string_factory(value):
    new_list = []
    for value in template:
        new_list.append(template.format(**value))
    return new_list

Hi Devin, you won't learn anything by having an easy time. When I first started I found programming really difficult, but it's something you keep working at :)

You've decided to call your list of dictionaries value, which means inside your function you can loop over it using:

for x in value:
    # do something with x

A good idea is to name your variables something meaningful, it helps to understand what's going on and your intent can be much more clearer to someone else reading your code.

def string_factory(list_of_dictionaries):
    new_list = []
    for single_dictionary in list_of_dictionaries:
        new_list.append(template.format(**single_dictionary))
    return new_list
