7,735 PointsWay off on the string_factory challenge?
I am a bit confused since we are dealing with a list of dictionaries, instead of a single dictionary. Not sure how that changes our approach but I have tried with no success. Anybody have a hint as to what I should focus on fixing here?
dicts = [
{'name': 'Michelangelo',
'food': 'PIZZA'},
{'name': 'Garfield',
'food': 'lasanga'},
{'name': 'Walter',
'food': 'pancakes'},
{'name': 'Galactus',
'food': 'worlds'}
]
string = "Hi, I'm {name} and I love to eat {food}!"
def string_factory(dicts,string):
strings = []
for item in dicts:
string.format(name, food)
strings.append(string)
return strings

Treehouse Guest TeacherYou're close! Your for loop is going through the list of dictionaries, so each item in it is a dictionary. When you call .format(), you need to either pass keywords and the values from the dict (.format(name=item['name']) or pass the dictionary in with **.

Treehouse Guest TeacherYou're missing a ) at the end of your string.format call.
You could just do string.format(**item), by the way, since item is a member of the dicts list.

13,675 PointsIt didn't click for me until I visually started looking at the list of dictionaries like I was calling them by index. You're correctly looping through the list, but like Kenneth pointed out you need to change how you're passing the format function your data. Ironically if you look at the video you make the same mistake Kenneth made at first. I used ** as it's easier.

7,735 PointsThanks for your comment Travis. I finally worked it out. I was able to make sense of what you were saying but I was still returning incorrectly due to the append function not working the way I thought it was. Thanks for helping me out!

7,735 PointsThanks Kenneth! I have been battling with this one throughout the day, even after reading your post but it finally just clicked because I wasn't appending the list correctly afterwards.

Treehouse Guest Teachernomadnick Way to go! Glad you solved it.
Have anything to share that I could change that might make easier/less confusing on future students?

7,735 PointsI think I mostly got thrown off because in the video I think it was focused on dictionaries and then the challenge was based on a list of dictionaries, which I don't think I have had much exposure to. Maybe just a little further explanation to students on how that will change the way to view the problem. Either way, hopefully these posts will serve as clarification for someone else that hits a roadblock.
