Pass the name of the label as an argument to the callback. Below is a
short working example:
from Tkinter import *
root = Tk()
def do_menu(l):
print 'menu pressed is ', l
menubar = Menu(root)
lab = 'test'
menubar.add_command(label=lab, command=lambda l=lab: do_menu(l))
lab = 'quit'
menubar.add_command(label=lab, command=lambda l=lab: do_menu(l))
root.config(menu=menubar)
root.mainloop()
