HI All,

I am new to the python, i am trying to call a method defined in the same class but getting an error as
" return self.func(*args)
TypeError: exitfunc() missing 1 required positional argument: 'self'"

The code is below : Trying to write a simple Menu window using tkinter.

from tkinter import *
import tkinter.messagebox
from tkinter.filedialog import askopenfilename

class menudiaplay:

    def __init__(self):
        self.exit = exit

    def function1(self):
     print("Menu is clicked")


    def openfile(self):
      name = askopenfilename()
      print(name)

    def function3(self):
       print("Undo is done")

    def exitfunc(self):
        self.exit = tkinter.messagebox.askquestion("Question", "Really want to exit")
        if self.exit == 'yes':
            self.root.destroy()
        else:
            print("Hello welcome back")


    root = Tk()
    mymenu = Menu(root)
    root.config(menu=mymenu)


    filesubmenu = Menu(mymenu)

    mymenu.add_cascade(label="File", menu=filesubmenu)

    filesubmenu.add_cascade(label="New Project", command=function1)
    filesubmenu.add_cascade(label="New", command=function1)
    filesubmenu.add_cascade(label="open File", command=askopenfilename)
    filesubmenu.add_cascade(label="Power save Mode", command=function1)
    filesubmenu.add_cascade(label="Exit", command=exitfunc)

    editsubmenu = Menu(mymenu)

    mymenu.add_cascade(label="Edit", menu=editsubmenu)

    editsubmenu.add_cascade(label="Undo", command=function3)

    toolbar = Frame(root, bg="light pink")
    insertbutton = Button(toolbar, text="Insert Files", command=function1)
    insertbutton.pack(side=LEFT, padx=2, pady=3)

    printbuttopn = Button(toolbar, text="Print", command=function1)
    printbuttopn.pack(side=LEFT, padx=2, pady=3)

    toolbar.pack(side=TOP, fill=X)

    status = Label(root, text="This is the status", bd=1, relief=SUNKEN, anchor=W)
    status.pack(side=BOTTOM, fill=X)

    root.mainloop()


b = menudiaplay()

Please help me.Thanks in advance.

change:

filesubmenu.add_cascade(label="Exit", command=exitfunc)

to:

filesubmenu.add_cascade(label="Exit", command=self.exitfunc)

Getting error as,

filesubmenu.add_cascade(label="Exit", command=self.exitfunc)
NameError: name 'self' is not defined

there are many things wrong with this script.
You are not using class properly.

much of what is here is outside of the class.
Use:

from tkinter import *
import tkinter.messagebox
from tkinter.filedialog import askopenfilename


class menudiaplay:
    def __init__(self, parent):
        self.parent = parent
        self.exit = exit
        mymenu = Menu(self.parent)
        self.parent.config(menu=mymenu)

        filesubmenu = Menu(mymenu)

        mymenu.add_cascade(label="File", menu=filesubmenu)

        filesubmenu.add_cascade(label="New Project", command=self.function1)
        filesubmenu.add_cascade(label="New", command=self.function1)
        filesubmenu.add_cascade(label="open File", command=askopenfilename)
        filesubmenu.add_cascade(label="Power save Mode", command=self.function1)
        filesubmenu.add_cascade(label="Exit", command=self.exitfunc)

        editsubmenu = Menu(mymenu)

        mymenu.add_cascade(label="Edit", menu=editsubmenu)

        editsubmenu.add_cascade(label="Undo", command=self.function3)

        toolbar = Frame(self.parent, bg="light pink")
        insertbutton = Button(toolbar, text="Insert Files", command=self.function1)
        insertbutton.pack(side=LEFT, padx=2, pady=3)

        printbuttopn = Button(toolbar, text="Print", command=self.function1)
        printbuttopn.pack(side=LEFT, padx=2, pady=3)

        toolbar.pack(side=TOP, fill=X)

        status = Label(self.parent, text="This is the status", bd=1, relief=SUNKEN, anchor=W)
        status.pack(side=BOTTOM, fill=X)

    def function1(self):
        print("Menu is clicked")

    def openfile(self):
        name = askopenfilename()
        print(name)

    def function3(self):
        print("Undo is done")

    def exitfunc(self):
        self.exit = tkinter.messagebox.askquestion("Question", "Really want to exit")
        if self.exit == 'yes':
            self.parent.destroy()
        else:
            print("Hello welcome back")

def main():
    root = Tk()
    menudiaplay(root)
    root.mainloop()

if __name__ == '__main__':
    main()
