Exceptions Handling Flask (Python)

I am using py_authorize 1.4. 

result = authorize.Transaction.sale({
            'amount': data2.price,
            'credit_card': {
                'card_number': card_number,
                'card_code': card_code,
                'expiration_date': month + '/' + year,
            }
        })
        result.transaction_response.trans_id
