如何在Tkinter Python的应用程序中删除视频？

import os
import tkinter as tk
from tkinter import messagebox

def delete_video():
    video_path = "path_to_video_file"  # 视频文件的路径
    if os.path.exists(video_path):
        os.remove(video_path)
        messagebox.showinfo("删除成功", "视频已成功删除！")
    else:
        messagebox.showerror("删除失败", "视频文件不存在！")

window = tk.Tk()
window.title("视频删除程序")
window.geometry("300x200")

# 创建一个按钮来触发删除视频函数
delete_button = tk.Button(window, text="删除视频", command=delete_video)
delete_button.pack()

window.mainloop()
