Watched the previous video a few times and still don't understand how to approach this question and what I'm doing wrong. Thank you very much in advance!
# 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(**list_of_dicts):
for dict in list_of_dicts:
string_factory(template.format(dict))
return list_of_dicts

- you probably don't want to call your function from inside your function
- you want to build a new list of strings to return, start by creating a new empty list
- the argument coming in is already a list, you don't need the unpacking operator there
- but you might want to do unpacking of the individual dictionaries as you format them
- the return is indented too far, right now it's inside the loop
- don't name a variable "dict", that's a reserved word
- finally, return the new list of strings (not the original list of dicts)

8,538 PointsThanks, Steven! I tried "append" a few times but that didn't work neither. Hope the code looks fine based on the markdown cheatsheet.
template = "Hi, I'm {name} and I love to eat {food}!"
def string_factory(list_of_dicts):
new = []
for dictionary in list_if_dicts:
new.append(template.format(**dictionary))
return new
```

You wrote "list_if_dicts" (with an "i") instead of "list_of_dicts" (with an "o").

8,538 PointsThank you, Steven! I tried again and again (with the limited knowledge I have) and I'm still stuck :( This is what I came up with based on your hints above:
def string_factory(list_of_dicts): new = [] for dictionary in list_of_dicts: new = template.format(**dictionary) return new

229,732 PointsThat's a bit tough to read without formatting! But assuming it's formatted correctly, the issue would be the assignment of "new" inside the loop. You set it up to be a list, but when you assign it with a string it's no longer a list. Plus, that wipes out any previously stored values.
So instead of an assignment, you need to do something that would add the string being created onto the list without affecting what's already there. Do you know a way to do that?
And when posting code, be sure to use the instructions for formatting in the Markdown Cheatsheet found below the "Add an Answer" area.
