Solve the following python programming problem given the following code:
@ quickcache (['country_code'], timeout = ((24 * 60) * 60)) 
def get_rate_table(self, country_code) : 
    backends = SQLMobileBackend.get_global_backends (SQLMobileBackend.SMS) 
    def _directed_fee(direction, backend_api_id, backend_instance_id) : 
        gateway_fee = SmsGatewayFee.get_by_criteria (backend_api_id, direction, backend_instance = backend_instance_id, country_code = country_code) 
        if (not gateway_fee) : 
            return None 
usd_gateway_fee = (gateway_fee.amount / gateway_fee.currency.rate_to_default) 
        usage_fee = SmsUsageFee.get_by_criteria (direction) 
        return fmt_dollar_amount ((usage_fee.amount + usd_gateway_fee)) 
rate_table = [] 
    from corehq.messaging.smsbackends.test.models import SQLTestSMSBackend 
    for backend_instance in backends : 
        if isinstance (backend_instance, SQLTestSMSBackend) : 
            continue 
if backend_instance.supported_countries : 
            if (('*' not in backend_instance.supported_countries) and (str (self) not in backend_instance.supported_countries)) : 
                continue 
gateway_fee_incoming = _directed_fee (INCOMING, backend_instance.hq_api_id, backend_instance.couch_id) 
        gateway_fee_outgoing = _directed_fee (OUTGOING, backend_instance.hq_api_id, backend_instance.couch_id) 
        if (gateway_fee_outgoing or gateway_fee_incoming) : 
            rate_table.append ({ 
                'gateway' : backend_instance.display_name, 
                'inn' : (gateway_fee_incoming or 'NA'), 
                'out' : (gateway_fee_outgoing or 'NA'),

return rate_table
