[Tutor] Copy/Paste in Tkinter

[Pooja Bhalode]

Hi,
I am trying to write a simple Tkinter code in Python in order to
demonstrate select/copy/paste/cut functionalities using keyboard keys and
menu options.
I tried looking up online, but I am finding examples of these in which they
create an event and then it is used:
eg.:

import Tkinter

def make_menu(w):
global the_menu
the_menu = Tkinter.Menu(w, tearoff=0)
# the_menu.add_command(label="Select")
the_menu.add_command(label="Cut")
the_menu.add_command(label="Copy")
the_menu.add_command(label="Paste")

def show_menu(e):
w = e.widget
# the_menu.entryconfigure("Select",command=lambda:
w.event_generate("<<Select>>"))
the_menu.entryconfigure("Cut",command=lambda: w.event_generate("<<Cut>>"))
the_menu.entryconfigure("Copy",command=lambda: w.event_generate("<<Copy>>"))
the_menu.entryconfigure("Paste",command=lambda:
w.event_generate("<<Paste>>"))
the_menu.tk.call("tk_popup", the_menu, e.x_root, e.y_root)

root = Tkinter.Tk()
make_menu(root)

e1 = Tkinter.Entry(); e1.pack()
e2 = Tkinter.Entry(); e2.pack()
e1.bind_class("Entry", "<Double-1><ButtonRelease-1>", show_menu)

root.mainloop()

I was wondering if someone could please tell me a simplified different way
of doing this, that would be great. Thank you.
