Retrieve right city from zip codes

Hi everyone!

I am trying to retrieve cities from zipcode_state. Here is the code:

Locations = pd.read_csv("geoloc1.csv", delimiter = ';')
Locations = Locations.drop_duplicates()
Locations['GEOLOC1'] = Locations['GEOLOC1'].str.rstrip() # Removing spaces at the right ot the nation name
Locations['CAP NAZIONE'] = Locations['GEOLOC1'].str.split('-').str[-1].str.strip() # Remove everything before -
Locations['CAP NAZIONE'] = Locations['CAP NAZIONE'].str.replace('_',' ') # Substitutes - with space 
Output = pd.DataFrame()

for index, row in Locations.iterrows():
time.sleep(1)
cap = row['CAP NAZIONE'].split(" ",1)[0]
nazione = row['CAP NAZIONE'].split(" ",1)[1]
loca = geocode(query = row['CAP NAZIONE'], addressdetails = True, language = 'it,en')
try:
    row['LOCATION'] = loca.raw['address']['city']
except:
    try:
        row['LOCATION'] = loca.raw['address']['hamlet']
    except:
        try:
            row['LOCATION'] = loca.raw['address']['county']
        except:
            row['LOCATION'] = '_'

if nazione == 'ITALIA':
    try:
        row['REGIONE'] = loca.raw['address']['state']
    except:
        '_'
Output = Output.append(row)

The problem is that fro certain zipcode_nazione it doesn't return the right city. For example: 23841_ITALIA it returns Avellaneda that is in Buenos Aires not in Italy.

How can I get the correct city? Is there something I am doing wrong or some more accurate method, package, library I can use?

Thanks, Carlotta.
