sqlalchemy engine.result.RowProxy to int in function with snowflake

I have searched the few questions with answers on SO with no luck.

like this one, and this one, or this one, and this one

I have a basic function that needs to read a log table, pull the max batch_id, and then create an object that is batch_id +1 and stored as a number/int.

it neither creates the objects, nor can I turn the sql results into anything readable other than a RowProxy or NoneType.

def sf_get_batchid():
engine = create_engine(
'snowflake://{user}:{password}@{account}/{database}/{schema}?warehouse=wh'.format(
    database='dev_db',
    schema='a_schema',
    user='user',
    password='password',
    account='account'
    )
)
connection = engine.connect()
print('Connected to DB: dev_db')
batchid_sql = "SELECT MAX(batch_id) FROM DEV_DB.A_SCHEMA.SN_DISTRIBUTION_LOG;" 
try:
    # execute sql
    result = connection.execute(batchid_sql)
    batch_id = result.fetchall()
    # return int(batch_id[0][0]) + 1
    new_batch_id = batch_id[0] +1
except Exception as e:
    print('Error: {}'.format(str(e)))
    sys.exit(1)

ultimately I want to just run this function with no args, and get two usable items

batch_id = the current max number
new_batch_id = that new number +1

thank you for any help.
