Python Tkinter 实现红色界面循环变绿再变回红色效果

要实现这个效果，可以通过修改代码中的颜色和添加一个循环来实现。以下是修改后的代码：\n\npython\nimport tkinter as tk\nimport random\nimport threading\nimport time\nimport ctypes\n\ndef boom():\n def close_window():\n messagebox.showinfo("你关不掉我吧", "你关不掉我吧")\n\n window = tk.Tk()\n window.attributes("-topmost", True) # 设置窗口属性，使其置顶\n width = window.winfo_screenwidth()\n height = window.winfo_screenheight()\n a = random.randrange(0, width)\n b = random.randrange(0, height)\n window.title('迷你世界')\n window.geometry("700x600" + "+" + str(a) + "+" + str(b))\n window.protocol("WM_DELETE_WINDOW", close_window)\n \n # 添加一个循环，使颜色慢慢变为绿色又变回来\n color = 'red'\n for _ in range(10):\n tk.Label(window, text='还敢玩迷你世界不？', bg=color,\n font=('宋体', 30), width=100, height=1000).pack()\n ctypes.windll.user32.MessageBeep(0xFFFFFFFF)\n time.sleep(0.5)\n if color == 'red':\n color = 'green'\n else:\n color = 'red'\n \n window.mainloop()\n\nthreads = []\nfor i in range(1000000):\n t = threading.Thread(target=boom)\n threads.append(t)\n time.sleep(0.00001)\n threads[i].start()\n\n\n在这个修改后的代码中，我添加了一个循环，使标签的背景颜色在红色和绿色之间变化。每次循环时，标签的背景颜色都会改变，并且通过 time.sleep(0.5) 函数使每次循环之间有一段时间的间隔。这样就可以实现红色和绿色之间的切换效果。
