如何使用for循环在tkinter中创建菜单？

import tkinter as tk

root = tk.Tk()

menu_bar = tk.Menu(root)
root.config(menu=menu_bar)

menu_items = ["文件", "编辑", "帮助"]

for item in menu_items:
    menu = tk.Menu(menu_bar)
    menu_bar.add_cascade(label=item, menu=menu)

root.mainloop()

import tkinter as tk

root = tk.Tk()

menu_bar = tk.Menu(root)
root.config(menu=menu_bar)

menu_items = ["文件", "编辑", "帮助"]

for item in menu_items:
    menu = tk.Menu(menu_bar)
    menu_bar.add_cascade(label=item, menu=menu)

root.mainloop()
