Iterate over list of dictionaries. Pass into function

Question

Disclaimer. I am new to python and trying to learn. I have a list of dictionaries containing address information I would like to iterate over and then pass into a function as arguments.

print(data)

[{'firstName': 'John', 'lastName': 'Smith', 'address': '123 Lane', 'country': 'United States', 'state': 'TX', 'city': 'Springfield', 'zip': '12345'}, {'firstName': 'Mary', 'lastName': 'Smith', 'address': '321 Lanet', 'country': 'United States', 'state': 'Washington', 'city': 'Springfield', 'zip': '54321'}]

I iterate over the list and attempt pass in the values, but the values are past as a list instead of individually. I'm not sure how to correct. I'm still grasping arguments and keyword arguments. Any help and guidance is appreciated.

from usps import USPSApi, Address

input_name = [li['lastName'] for li in data]
input_address = [li['address'] for li in data]
input_city = [li['city'] for li in data]        
input_state = [li['state'] for li in data]        
input_zip = [li['zip'] for li in data]        
input_country = [li['country'] for li in data]  

address = Address(
    name = input_name,
    address_1= input_address,
    city= input_city,
    state=input_state,
    zipcode=input_zip
)
usps = USPSApi('------', test=True)
validation = usps.validate_address(address)
data_results = validation.result 
print(data_results)

You already have all the logic to process a single data point, just expand it to multiple data points as shown below using a loop.

from usps import USPSApi, Address

for item in data:
    kwargs = dict()

    kwargs['name'] = item['lastName']
    kwargs['address_1'] = item['address']
    kwargs['city'] = item['city']
    kwargs['state'] = item['state']
    kwargs['zipcode'] = item['zip']

    address = Address(**kwargs)

    usps = USPSApi('------', test=True)
    validation = usps.validate_address(address)
    data_results = validation.result 
    print(data_results)

Without syntactic sugar it becomes

for item in data:
    kwargs = dict()

    name = item['lastName']
    address_ = item['address']
    city = item['city']
    state = item['state']
    zip_ = item['zip']

    address = Address(
        name=name,
        address_1=address_,
        city=city,
        state=state,
        zipcode=zip_)
