如果我在tkinter中输入了错误的密码，它不能处理while循环

import tkinter as tk

def check_password():
    password = entry.get()
    correct_password = "123456"  # 正确的密码

    if password == correct_password:
        label.config(text="密码正确")
    else:
        label.config(text="密码错误，请重新输入")

# 创建窗口
window = tk.Tk()

# 创建密码输入框
entry = tk.Entry(window, show="*")
entry.pack()

# 创建按钮
button = tk.Button(window, text="确认", command=check_password)
button.pack()

# 创建用于显示结果的标签
label = tk.Label(window, text="")
label.pack()

# 进入主循环
window.mainloop()

import tkinter as tk

def check_password():
    password = entry.get()
    correct_password = "123456"  # 正确的密码

    while password != correct_password:
        label.config(text="密码错误，请重新输入")
        password = entry.get()

    label.config(text="密码正确")

# 创建窗口
window = tk.Tk()

# 创建密码输入框
entry = tk.Entry(window, show="*")
entry.pack()

# 创建按钮
button = tk.Button(window, text="确认", command=check_password)
button.pack()

# 创建用于显示结果的标签
label = tk.Label(window, text="")
label.pack()

# 进入主循环
window.mainloop()
