python - Tkinter menubar class -

i'm trying make code more efficient have class creating menu bar , contents. no errors being reported, won't make bar. (i did have working without class, can't seem working again!)

from tkinter import *  class menubar: #'player' name of tk window     def __init__(self, menuname, label, drop_label, command, separator = false):         self.menubar = menu(player)         self.menuname = menu(self.menubar, tearoff = 0)         self.menuname.add_command(label = label, command = command)          if separator == true:             self.menuname.add_separator()          self.menubar.add_cascade(label = drop_label, menu = menuname)          self.create()      def create(self):         player.config(menu = self.menubar)  #example menu item def addmenubar():     exitmenu = menubar("filemenu", "exit", "file", onexit, true)     #more menu items here, function keep tidier.  def onexit():     #code here  player = tk()  addmenubar()  player.mainloop() 

this draw tk window, no menu bar options, going wrong? cheers.

in __init__ function create menu bar.
create function adds menus , accept commands list of tuples:

from tkinter import *  class menubar: #'player' name of tk window     def __init__(self, parent):         self.menubar = menu(parent)         self.create()      def create(self):         player.config(menu = self.menubar)      def add_menu(self, menuname, commands):         menu = menu(self.menubar, tearoff = 0)          command in commands:             menu.add_command(label = command[0], command = command[1])             if command[2]:                 menu.add_separator()          self.menubar.add_cascade(label=menuname, menu=menu)  def onexit():     import sys     sys.exit()  def onopen():     print 'open'  player = tk()  menubar = menubar(player)  filemenu = menubar.add_menu("file", commands = [("open", onopen, true), ("exit", onexit, false)])  player.mainloop()
