使用tkinter中的按钮开始/停止循环

import tkinter as tk

window = tk.Tk()

label = tk.Label(window, text="循环未开始")
label.pack()

is_running = False

def start_loop():
    global is_running
    is_running = True
    label.config(text="循环进行中")
    # 在这里编写循环的具体逻辑

def stop_loop():
    global is_running
    is_running = False
    label.config(text="循环已停止")

start_button = tk.Button(window, text="开始循环", command=start_loop)
start_button.pack()

stop_button = tk.Button(window, text="停止循环", command=stop_loop)
stop_button.pack()

window.mainloop()
