How to link a GUI (tkinter) script to another script?

Question

Python

There is some script, which is a sequential set of instructions, in some places requiring user input, or giving data to the user.
There is a second script that provides some simple GUI (tkinter) for user interaction.
Actually, the question is: what is the easiest way to connect one with the other and organize their interaction? Threads?

Answer 1

There is a book Python in Practice, in which such examples are considered - both threads and processes. Code examples here www.qtrac.eu/pipbook.html
