[Tkinter-discuss] How to display the values of dictionary to tk window.

[Srinivas Rao]

This code is to receive and display the text on the tk window.But what
i want to achieve here is: When the character is sent from master to
slave. Receive the character on the slave, look up the character in
the dict, display the value that corresponds to the key. I tried but
couldn't succeed, can any one help me with the correct code.

for example: when slave received a key called 'hw' from master,It has
to display "hello world" on slave pc , when '0' received from master,
should display "how are you?" on slave pc. thanks in advance.
