重新启动程序tkinter

Question

我想知道如何创建一个重新启动按钮，单击该按钮可以重新启动整个脚本。我以为您先破坏窗口然后销毁它，但是显然没有销毁功能。

我在以下网站上找到了用于通用python程序的方法：https : //www.daniweb.com/programming/software-development/code/260268/restart-your-python-program。我用基本的tkinter GUI编写了一个示例来对其进行测试：

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()
