How To Save Telegram Python Variable Value To Local Database?

Sorry, i am newbie in python

i have problem to save variable in python bot telegram into localhost. How to save the value of python bot telegram variable into the local database? Like the following variables

user.sex,user.age, user.q27

I've made a connection like the this

con = pymysql.connect(db="python", user="root", passwd="",host="localhost",port=3306,autocommit=True) 
cur = con.cursor()

And try to execute the query in process_data

chat_id = message.chat.id
  q27 = message.text
  user = user_dict[chat_id]
  user.q27 = q27

  cur.execute("INSERT INTO diagnosa (sex, age, jawaban) VALUES (%s, %s, %s)" (user.sex,user.age, user.q27))

  msg = bot.send_message(chat_id, 'Nice to meet you ' + user.name + '\n Age:' + str(user.age) + '\n Sex:' + user.sex + '\n jawaban:' + user.q27 )
  bot.register_next_step_handler(msg, send_end)

Complete code

import pymysql

import time

import telebot
from telebot import types

API_TOKEN = ''

bot = telebot.TeleBot(API_TOKEN)

user_dict = {}

con = pymysql.connect(db="python", user="root", passwd="",host="localhost",port=3306,autocommit=True)
cur = con.cursor()


class User:
  def __init__(self, name):
  self.name = name
  self.age = None
  self.sex = None
  self.q27 = None

@bot.message_handler(commands=['help', 'start'])

@bot.message_handler(commands=['help', 'start'])
def send_welcome(message):
  msg = bot.reply_to(message, """\
Siapa Nama Anda?
""")
  bot.register_next_step_handler(msg, process_name_step)

def process_name_step(message):
  try:
    chat_id = message.chat.id
    name = message.text
    user = User(name)
    user_dict[chat_id] = user
    msg = bot.reply_to(message, 'Berapakah umur anda?')
    bot.register_next_step_handler(msg, process_age_step)
  except Exception as e:
    bot.reply_to(message, 'Kesalahan name step')

def process_age_step(message):
  try:
    chat_id = message.chat.id
    age = message.text
    if not age.isdigit():
    msg = bot.reply_to(message, 'Umur haruslah sebuah angka. Berapakah usia anda?')
    bot.register_next_step_handler(msg, process_age_step)
    return
    user = user_dict[chat_id]
    user.age = age
    markup = types.ReplyKeyboardMarkup(one_time_keyboard=True)
    markup.add('Pria', 'Wanita')
    msg = bot.reply_to(message, 'Apakah jenis kelamin anda?', reply_markup=markup)
    bot.register_next_step_handler(msg, process_q27_step)
  except Exception as e:
    bot.reply_to(message, 'Kesalahan age step')

def process_data(message):
  try:
   chat_id = message.chat.id
   q27 = message.text
   user = user_dict[chat_id]
   user.q27 = q27

   cur.execute("INSERT INTO diagnosa (sex, age) VALUES (%s, %s, %s)" (user.sex,user.age, user.q27))

   msg = bot.send_message(chat_id, 'Nice to meet you ' + user.name + '\n Age:' + str(user.age) + '\n Sex:' + user.sex + '\n jawaban:' + user.q27 )
   bot.register_next_step_handler(msg, send_end)
  except Exception as e:
   bot.reply_to(message, 'oooops')

def send_end(message):
   msg = bot.reply_to(message,"""Byeee""")

bot.polling()

finally I get the solution of the problem. I do not need cur = con.cursor ().

Before writing the query, we need to write

with con.cursor () as cursor:

sql = "query" cursor.execute (sql)
con.commit ()
con.close ()
