сам листинг вот:

db = pymysql.connect('localhost', 'chellas', '123', 'superbot')



bot = telebot.TeleBot(TOKEN)
print('Start Server')



keyboard1 = telebot.types.ReplyKeyboardMarkup(True, True)
keyboard1.row('Мои боты', 'Тарифы')

@bot.message_handler(commands=['start'])
def start(message):
    send_mess = f"<b>Hi {message.from_user.first_name}</b>\n" \
        f"Добро пожаловать на <b>SuperBot</b>"
    bot.send_message(message.chat.id, send_mess, parse_mode='html', reply_markup=keyboard1)
    send_mess2= f"Твой баланс:"
    bot.send_message(message.chat.id, send_mess2)
    user_id = message.from_user.id
    username = message.from_user.username
    print(username)

    sql_query = f"""insert into users (telegram_id) values (23)"""


    cursor = db.cursor()
    cursor.execute(sql_query)
    cursor.close()
    db.commit()
    print ("INSERT SECCESSFULLY")



db.close()
