如何在python tkinter中一次显示一个窗口？

import tkinter as tk

window = tk.Tk()

window.title("窗口标题")
window.geometry("500x500")  # 窗口大小为500x500

label = tk.Label(window, text="这是一个窗口")
label.pack()  # 将标签放置在窗口中

button = tk.Button(window, text="点击按钮")
button.pack()  # 将按钮放置在窗口中

window.mainloop()

import tkinter as tk

window = tk.Tk()
window.title("窗口标题")
window.geometry("500x500")

label = tk.Label(window, text="这是一个窗口")
label.pack()

button = tk.Button(window, text="点击按钮")
button.pack()

window.mainloop()
