please see the code below, is there any way to convert tkinter code to pyqt5?

Code:

from tkinter import *

from tkinter import ttk

from tkinter import messagebox

def connection():

connectObj = db.connect("shopManagement.db")

cur = connectObj.cursor()

sql = '''

create table if not exists sellings (

date string,

product string,

price number,

quantity number,

total number

)

'''

cur.execute(sql)

connectObj.commit()

connection()

window=Tk()

window.title("TechVidvan Shop Management Project")

tabs = ttk.Notebook(window)

root= ttk.Frame(tabs)

root2=ttk.Frame(tabs)

tabs.add(root, text ='Sell')

tabs.add(root2, text ='Stock')

tabs.pack(expand = 1, fill ="both")
