You have to think in terms of the python objects.
geoNames API gives you a dictionary with one key: postalcodes
The value of the postalcodes entry in the dictionary is a list of
dictionaries, each with the info of one postal code.
If the list is empty the previous code
for x in location_data['postalcodes']:
should work since there would be nothing to iterate over (you never get a
value for x and the 'for' never loops).
