# Connect to the database

connection = pymysql.connect(host='localhost',

                            user='user',

                            password='passwd',

                            db='db',

                            charset='utf8mb4',

                            cursorclass=pymysql.cursors.DictCursor)

try:

   with connection.cursor() as cursor:

       # Create a new record

       sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"

       cursor.execute(sql, ('webmaster@python.org', 'very-secret'))

   # connection is not autocommit by default. So you must commit to save

   # your changes.

   connection.commit()

   with connection.cursor() as cursor:

       # Read a single record

       sql = "SELECT `id`, `password` FROM `users` WHERE `email`=%s"

       cursor.execute(sql, ('webmaster@python.org',))

       result = cursor.fetchone()

       print(result)

finally:

   connection.close()
