How do I add logging errors in my lambda function?

I added a few, I'm not sure if any more would be useful. Also, is this all I have to do to write a lambda? I was given very little instruction on how to do it. It returns the result from the query like it's supposed to. I don't see anything wrong with it except for adding some logging exceptions?

import logging
import os
import sys
import mariadb as mdb

cnxn = mdb.connect(
user="username",
password="pass",
host="host",
port=port,
database="database"
)

cur=cnxn.cursor()
SQL_QUERY="CALL STORED_PROCEDURE();"
cur.execute(SQL_QUERY)
row=cur.fetchone()

def name_of_handler(event=None, context=None):
    try:
        cur.execute(SQL_QUERY)
        cnxn.commit()
    except mdb.Error as e:
        print(f"Error: {e}")
    except Exception as e:
        logging.exception(e)

    print(row)
    cnxn.close()

name_of_handler()

UPDATE: Nevermind, how do I write a message saying "executed successfully?" I see the records did insert into the database, but there is no confirmation in the python code.
