python - 重启程序 tkinter

Question

我想知道如何创建一个重启按钮，点击后可以重启整个脚本。我的想法是先销毁窗口然后取消销毁它，但显然没有取消销毁功能。

我在这个网站上找到了一种为通用 python 程序执行此操作的方法:https://www.daniweb.com/programming/software-development/code/260268/restart-your-python-program .我用基本的 tkinter GUI 写了一个例子来测试它:

import sys
import os
from tkinter import Tk, Label, Button

def restart_program():
    """Restarts the current program.
    Note: this function does not return. Any cleanup action (like
    saving data) must be done before calling this function."""
    python = sys.executable
    os.execl(python, python, * sys.argv)

root = Tk()

Label(root, text="Hello World!").pack()
Button(root, text="Restart", command=restart_program).pack()

root.mainloop()
