Запись переменной в базу данных Python

Всем привет. Реализовал простую игру типа Cookie Clicker на Python. Вот ее код целиком:

from tkinter import *
from PIL import ImageTk, Image
import threading
from tkinter import messagebox
import time
from tkinter import PhotoImage
from tkinter import ttk
#---------------------------------------------------------------------------

cookies = 0

root = Tk()
root.title("Cookie Clicker")
root.resizable()
root.resizable(width=False, height=False)
root.iconphoto(True, PhotoImage(file='icon.png'))
root.configure(bg="white")

tabControl = ttk.Notebook(root)
cookieTab = ttk.Frame(tabControl)
shopTab = ttk.Frame(tabControl)
tabControl.add(cookieTab, text="Cookie")
tabControl.add(shopTab, text="Shop")
tabControl.grid(row=0, column=0, sticky="w")
#---------------------------------------------------------------------------

def bake():

    global cookies

    cookies += 1
    cookieCounter1.config(text=f"Cookies: {cookies}")
    cookieCounter2.config(text=f"Cookies: {cookies}")


#Granny

def newGranny():

    global cookies

    while True:
        time.sleep(1)
        cookies += 5
        cookieCounter1.config(text=f"Cookies: {cookies}")
        cookieCounter2.config(text=f"Cookies: {cookies}")

def addGranny():

    global cookies

    if cookies >= 100:

        gran = threading.Thread(target=newGranny)
        gran.setDaemon(True)
        gran.start()

        cookies -= 100


    else:
        messagebox.showinfo("Granny", "Sorry you don't have enough cookies to hire a granny")

#Clicker

def newClicker():

    global cookies

    while True:
        time.sleep(1)
        cookies += 1
        cookieCounter1.config(text=f"Cookies: {cookies}")
        cookieCounter2.config(text=f"Cookies: {cookies}")

    if cookies >= 10:

        click = threading.Thread(target=newClicker)
        click.setDaemon(True)
        click.start()

        counter = create_counter()

        cookies -= 10 + counter()

    global cookies

    if cookies >= 1000:

        rats = threading.Thread(target=newRat)
        rats.setDaemon(True)
        rats.start()

        cookies -= 1000


    else:
        messagebox.showinfo("Rat", "Sorry you don't have enough cookies to buy a rat")

    global cookies

Тут еще используется 6 изображений. Так вот, игра запускается и нормально функционирует, однако стало интересно, как можно прикрутить к этому всему базу данных, чтобы можно было в нее вносить переменную cookies для того, чтобы игра могла продолжаться с того же места после ее закрытия и нового открытия?
