连接窗口登录和窗口菜单

Question

如何将窗口登录与窗口菜单连接。我需要在单击按钮“connecter”后显示窗口菜单并隐藏窗口登录。我在窗口菜单中有更多的代码行，但我只想知道原理。 我试图在if row:中添加 root.deiconify()和 log.withdraw。但是显示了一个错误

文件“c:\Users\user\Desktop\traitement images\PFE\u codage\Menu.py”，第26行，登录 root.deiconify（）#messagebox.showinfo（“登录成功”） NameError:未定义名称“根”

这是我的密码：

窗口登录

from tkinter import Tk, Label, Entry, Button, Frame,messagebox,StringVar
import tkinter as tk 
import sqlite3
from tkinter import *

def login():
    db=sqlite3.connect('login.sqlite')
    db.execute('CREATE TABLE IF NOT EXISTS user(username TEXT, password TEXT)')
    db.execute("INSERT INTO user(username, password) VALUES('salma', 'salma2001')")
    db.execute("INSERT INTO user(username, password) VALUES('zineb', 'zineb1994')")
    cursor=db.cursor()
    cursor.execute("SELECT * FROM user where username=? AND password=?",(user_input.get(), pass_input.get()))
    row=cursor.fetchone()
    if row:
        root.deiconify() #messagebox.showinfo("login success")
        #log.withdraw()
    else:
        messagebox.showinfo("échec de connexion", "nom d'utilisateur ou mot de passe incorrect")
    cursor.connection.commit()
    db.close()

log = Tk()
log.geometry('350x500')
log.title('CONNEXION')
log.resizable(0,0)

j = 0

for i in range(100):

log.mainloop()

窗口菜单

color = {"nero":  '#846160': "#FF8700" :"gray17"}

# setting root window:
root = Tk()
root.title("Page d'accueil")
root.config(bg="gray17")
#root.geometry("400x600+850+50")
root.geometry("800x600+850+50")

# window in mainloop:
root.mainloop()
