Json array into list of class

Question

Having this json

[{'id': '16166cf3', 'quote': 'a.'}, {'id': '16166cfb', 'quote': 'b.'} ]

And this Class

class Quotes:
    def __init__(self, id, quote):
        self.id = id
        self.quote = quote

How can I transform the json arrayList into a list of Quotes??

For now I have this

with open("../json/quotes.json") as json_file:
            quote_list = json.load(json_file)
            print(quote_list)

Regards

Loop over the parsed list, and for each dict in the list, construct an instance of Quote with the fields from the dict. You can then append these instances to a new list.

with open("../json/quotes.json") as json_file:
    quote_list = json.load(json_file)
    print(quote_list)

instances = []

for q in quote_list:
    instances.append(Quotes(q["id"], q["quote"]))

More compact form using list comprehension, and assigning to the same variable:

with open("../json/quotes.json") as json_file:
    quote_list = json.load(json_file)
    print(quote_list)
    quote_list = [Quotes(q["id"], q["quote"]) for q in quote_list]

thanks, there's nothing more functional to transform from A to B?
