如何删除 tkinter 中的菜单栏？

Question

我知道我可以使用add_cascade 如下代码创建菜单栏：

from tkinter import * 
from tkinter.ttk import * 
from time import strftime
  
# creating tkinter window
root = Tk()
root.title('Menu Demonstration')
  
# Creating Menubar
menubar = Menu(root)
  
# Adding File Menu and commands
file = Menu(menubar, tearoff = 0)
menubar.add_cascade(label ='File', menu = file)
file.add_command(label ='New File', command = None)
file.add_command(label ='Open...', command = None)
file.add_command(label ='Save', command = None)
file.add_separator()
file.add_command(label ='Exit', command = root.destroy)
  
# Adding Edit Menu and commands
edit = Menu(menubar, tearoff = 0)
menubar.add_cascade(label ='Edit', menu = edit)
edit.add_command(label ='Cut', command = None)
edit.add_command(label ='Copy', command = None)
edit.add_command(label ='Paste', command = None)
edit.add_command(label ='Select All', command = None)
edit.add_separator()
edit.add_command(label ='Find...', command = None)
edit.add_command(label ='Find again', command = None)
  
# Adding Help Menu
help_ = Menu(menubar, tearoff = 0)
menubar.add_cascade(label ='Help', menu = help_)
help_.add_command(label ='Tk Help', command = None)
help_.add_command(label ='Demo', command = None)
help_.add_separator()
help_.add_command(label ='About Tk', command = None)
  
# display Menu
root.config(menu = menubar)
mainloop()

但我怎样才能删除它们呢？

您可以使用delete删除菜单栏

menubar.delete ( 'name' )
