unpacking dictionary

Please take a look at this task and advise why it doesn't work. The unpacking task is a little confusing to me.

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}!"
def string_factory (values):
    new_list_strings = []
    for items in values:
        if name and food:
            new_list_strings.append (template.format(**values))

    return new_list_strings

You are very close!

  • the if name and food: is not needed
  • use items instead of values in new_list_strings.append (template.format(**values))

Think about this for a second

# Example:
in_data = [  {"name": "Michelangelo", "food": "PIZZA"}, 
          {"name": "Garfield", "food": "lasagna"}

          ]

template = "Hi, I'm {} and I love to eat {}!"


for some_dict in in_data:
      print(template.format(some_dict.get('name'), some_dict.get('food')))

Hi, I'm Michelangelo and I love to eat PIZZA!
Hi, I'm Garfield and I love to eat lasagna!
