You can use the widget's bind() method to replace the standard callback with a new one:

from Tkinter import *
root = Tk()
e = Entry(r)

def PtoT(event):
    e.insert('insert', 't')
    return 'break'

e.bind('<p>', PtoT)

the "return 'break'" statement prevents the event from being propagated to Tk's standard event handler;
without it both "p" and "t" would be inserted into the Entry.

I hope this helps
