Tkinter Unknown Option -menu

I keep getting the error: _tkinter.TclError: unknown option '-menu' My MWE looks like: from tkinter import * def hello(): print('hello!') class Application(Frame):

Solution 1:

self.config(menu=self.menuBar)

menu is not a valid configuration option for Frame.

Perhaps you meant to inherit from Tk instead?

from tkinter import *

defhello():
    print("hello!")

classApplication(Tk):
    defcreateWidgets(self):       
       self.menuBar = Menu(master=self)
       self.filemenu = Menu(self.menuBar, tearoff=0)
       self.filemenu.add_command(label="Hello!", command=hello)
       self.filemenu.add_command(label="Quit!", command=self.quit)
       self.menuBar.add_cascade(label="File", menu=self.filemenu)

    def__init__(self):
       Tk.__init__(self)
       self.createWidgets()
       self.config(menu=self.menuBar)

if __name__ == "__main__":
    ui = Application()
    ui.mainloop()
