[Tutor] Changing Keyboard output

[Igor Riabtchuk]

Hi,

I am totally new to Python and still 
learning.

I am looking for a way to change keyboard output 
within Tkinter widget - for example, say I press "p" and I want it to come out 
as "t".

Could anyone possibly point me in the right 
direction?

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)
e.pack()

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

Take a look at the Event Driven programming topic in my tutor, 
it covers reading keyboard input in Tkinter.
