Thanks Denes, it worked. Here is snippet from my app:
location_data =
json.loads(fetch('http://api.geonames.org/postalCodeLookupJSON?postalcode=%s&username=my_user_name'
% your_postal_code))
there_is_data = False
for x in location_data['postalcodes']:
there_is_data=True
if there_is_data == False:
redirect(URL('go_to_one_function'))
else:
redirect(URL('go_to_a_different_function'))
